Definitions
- the application relates to a monitoring circuit for a programmable gate arrangement, an arrangement with a monitoring circuit, processor and programmable gate arrangement and a method for operating such an arrangement.
- a programmable gate array is a digital integrated circuit that is located on a board and into which a logic circuit can be loaded. The logic circuit can be used to execute functions and process signals.
- An example of a programmable gate array is an FPGA (Field Programmable Gate Array).
- Another example of a programmable gate array is a SoC (System on Chip) component.
- Programmable gate arrays are used, for example, in Rapid Control Prototyping (RCP) or Hardware in the Loop (HiL) real-time systems.
- Simulation models of such real-time systems are examples of functions that can be executed on the programmable gate arrays.
- Values of signals from the simulation models can be queried by a user during simulation runtime, for example via dSPACE ControlDesk, and output to the user.
- EP3244326 describes a shadow register of an FPGA that is intended to store the value of a signal of the FPGA. The value of the signal can be read out during the runtime of a function of the FPGA, whereby the reading of the shadow register is functionally independent of the execution of the function.
- EP2765528 describes a method that enables access to the value of a signal of an FPGA at runtime. For this purpose, FPGA state data is read out during operation and the signal value is determined from this.
- a programmable gate arrangement is configured to execute a function and to use at least one signal to execute the function.
- a processor is configured to execute a higher-level function and to transfer a value of the at least one signal to the gate arrangement and/or to receive a value of the at least one signal from the gate arrangement to execute the higher-level function.
- a monitoring circuit is configured to exchange a value of the at least one signal with the gate arrangement, the exchange of the value of the signal taking place independently of the function executed on the gate arrangement. The monitoring circuit is further configured to exchange the value of the at least one signal with the processor.
- the exchange of the value of the signal between the gate arrangement and the monitoring circuit is preferably carried out via a memory of the gate arrangement.
- the programmable gate arrangement in particular an FPGA or a SoC component, is often used for time-critical simulation calculations, such as HiL simulations (hardware-in-the-loop).
- a function of the gate arrangement can include the execution of these time-critical simulations, which are carried out cyclically at runtime - e.g. at a clock frequency of the gate arrangement.
- the processor executes the higher-level function, which interacts with the function executed on the gate arrangement, for example for time-critical and/or computationally intensive components.
- the processor transfers at least one value of the at least one signal to the gate arrangement and/or receives at least one value of the at least one signal from the gate arrangement.
- the exchange of values between the processor and the gate arrangement to execute the function or the higher-level function is carried out via communication interfaces provided for this purpose. These can be registers, buffers or bus interfaces, for example.
- the exchange of the signal value between the gate arrangement and the monitoring circuit takes place independently of the execution of the function on the gate arrangement. This is an advantage because the sequence of the function, e.g. the simulation, is not disrupted. In comparison to the state of the art, another advantage is the increased flexibility of the information exchange between the gate arrangement and its periphery.
- a shadow register associated with the signal can be provided, which is set up and intended to store the value of the associated signal.
- the shadow register is a memory of the programmable gate arrangement in which a value of the associated signal is stored while the function of the gate arrangement is being carried out.
- the shadow register has a transmission channel to the monitoring circuit, via which the value stored in the shadow register can be transmitted to the monitoring circuit.
- the latter transmission channel is implemented by means of a so-called ICAP interface in the gate arrangement.
- ICAP Internal Configuration Access Port
- ICAP Internal Configuration Access Port
- a dedicated memory of the gate arrangement can be provided, which the function executed on the gate arrangement has read access to.
- the monitoring circuit can have write access to this area and write the value to be exchanged by writing into the memory.
- the memory is designed as a shift register chain.
- the dedicated memory has a transmission channel to the monitoring circuit, via which the value to be written can be transmitted from the monitoring circuit.
- the exchange of the value of the at least one signal comprises in particular a reading and/or writing of the at least one signal by the monitoring circuit.
- the exchange of the value can comprise, for example, a reading of the value of the signal from a memory of the gate arrangement by the monitoring circuit.
- the reading of the value of the signal from the memory of the gate arrangement takes place independently of the function executed on the gate arrangement.
- the exchange of the value can comprise, for example, a writing of the value into a memory of the gate arrangement.
- the writing of the value of the signal into the memory of the gate arrangement takes place independently of the function executed on the gate arrangement.
- the gate arrangement is configured to receive a value of the at least one signal for processing from the processor, to process the value of the signal during execution of the function, and to output the processed value of the signal to the processor. This makes it possible to have parts of the higher-level function executed as a function of the gate arrangement. Signal values calculated by the function of the gate arrangement can then be further used by the higher-level function of the processor.
- a value of the at least one signal is present in the gate arrangement.
- the gate arrangement is set up to derive a value of the at least one signal from a read-out sensor value.
- the signal can be a value that is used by the function, such as a measured value or a value of a variable of the function.
- a signal can also be a purely calculated value, e.g. a value converted from a measured value or an intermediate value.
- the at least one signal can be implemented as a constant and the gate arrangement is configured to use the constant during the execution of the function.
- a constant comprises values that are not intended to be changed during the execution of the function, but can be changed by the monitoring circuit.
- the monitoring circuit is configured to write a value of the at least one constant into a memory of the gate arrangement, wherein the value of the constant is written independently of the the function executed by the gate arrangement.
- the monitoring circuit is further configured to receive the value to be written for the constant from the processor.
- Values of constants can be, for example, parameter values used to parameterize a simulation. This offers the advantage that the processor can change the constant, e.g. from the execution of the higher-level function, without interfering with the execution of the function of the gate arrangement.
- the monitoring circuit is set up to read the value of the constant from a memory of the gate arrangement and to output the read value to the processor. This makes it possible for the processor to access the current value of the constant present in the gate arrangement. This can be done from the currently executed higher-level function without interfering with the execution of the function of the gate arrangement.
- the value of the constant can, for example, be predefined or derived from a calculation on the gate arrangement or read from a sensor connected to the gate arrangement.
- the monitoring circuit is configured to receive a value of the constant to be written from an operating unit, wherein the operating unit is configured to receive the value to be written from a user. This enables the additional possibility of having the value of the at least one constant to be written determined by a user.
- the monitoring circuit is, for example, configured to output a read value of the signal to the operating unit, wherein the operating unit is configured to output the read value to a user.
- the monitoring circuit is configured to receive information from the processor about the signal whose value is to be read from the memory of the gate arrangement.
- the information allows the monitoring circuit in particular to identify the signal that is to be read out. This is particularly relevant in the case of several readable signals, since in such cases the monitoring circuit is to be informed must decide which of the readable signals it should read.
- the information about the signal can also be information about the memory where the value of the signal is stored and, for example, made available for reading by the monitoring circuit.
- the monitoring circuit can be set up to receive information about the signal to be read from the control unit.
- the monitoring circuit can then be set up to read the value of the signal for which it has received the information from a memory of the gate arrangement and then transmit the read value to the control unit, e.g. for output to the user.
- the information allows the monitoring circuit to identify the signal to be read, for example.
- An arrangement comprises the described monitoring circuit as well as the processor and the programmable gate arrangement.
- the value of the signal received by the monitoring circuit can be used by the processor when executing the higher-level function. This enables access to, for example, a variable of the function of the gate arrangement, for example for monitoring purposes, without disturbing or delaying the execution of the function on the gate arrangement.
- the value of the constant passed by the processor to the monitoring circuit can be generated by the processor when executing the higher-level function. This makes it possible to change one or more constants stored on the gate arrangement and used to execute the function without affecting the execution of the actual function.
- the gate arrangement has at least one memory arrangement which can be addressed via configuration bits and data bits.
- the monitoring circuit is set up here to read and/or write the at least one memory arrangement.
- Such a memory arrangement has at least one memory area, which is preferably designed as a so-called block RAM of the programmable gate arrangement.
- the gate arrangement preferably has a converter between the monitoring circuit and the at least one memory arrangement which is set up to serialize the configuration bits and the data bits and to transmit them in serial form. The converter can also be set up to deserialize the configuration bits and data bits received in serial form.
- the gate arrangement has a transmission channel between the converter and the at least one memory arrangement, which is set up to transmit serialized configuration bits and data bits. This makes it possible to transmit the serial data converted by the converter to the memory arrangement. It is further proposed that the gate arrangement has a further transmission channel between the at least one memory arrangement and the converter, which is set up to transmit serialized configuration bits and data bits.
- the memory arrangement can further comprise a deserializer for each memory area, via which the configuration bits and data bits received serially via the transmission channel can be deserialized in order to then be able to address the memory area in a suitable parallel form.
- the memory arrangement can further comprise a serializer for each memory area, via which the configuration bits and data bits received in parallel from the memory area can be serialized in order to then be transmitted to the converter in a suitable serial form via the further transmission channel.
- the converter and the transmission channels provided enable access to the memory area or memory areas of the memory arrangement, which requires only a few transmission channels between the converter and the memory arrangement. For example, it is possible to use one transmission channel for the transmission from the converter to a memory area and another transmission channel for the transmission from the memory area to the converter, i.e. two transmission channels per memory area. In a further embodiment, more than two transmission channels are allocated per memory area. The latter embodiment is characterized by the fact that although more routing resources are used in the gate arrangement, a higher total data transmission rate is regularly enabled, for example by allocating more than two transmission channels.
- the arrangement comprises an operating unit which is configured to receive the value of the signal to be written from a user and to transmit it to the monitoring circuit and/or to receive the read value of the signal from the monitoring circuit and to output it to the user.
- a method for operating the described arrangement comprises:
- FIG. 1 shows schematically an arrangement which comprises a programmable gate arrangement, a processor and an operating unit
- Figures 2-4 show a schematic representation of examples of exchangeable values in a modelling language
- Figure 5 is a schematic view of a programmable gate array with memory array.
- Figure 1 schematically shows an arrangement which comprises a programmable gate arrangement 10, a processor 30 and an operating unit 50.
- the processor 30 is arranged on a processor board and has a real-time library RLI, which provides interfaces to a higher-level function 32 and to a driver 20.D.
- the processor 30 is set up to execute the higher-level function 32.
- Variables 34 are used to execute the higher-level function 32.
- Exchange values 36 are also used to execute the higher-level function 32.
- mirrored values 36.M of the exchange values 36 of the higher-level function 32 are present.
- the mirrored values 36.M and 36 are kept at the same level by the driver 20.D.
- the exchange values 36 are used by the higher-level function 32 and/or the driver 20. D checks using suitable methods whether the mirrored values 36.
- M have the same value as the exchange values 36.
- their identity check is preferably omitted until a predefined condition, e.g. the expiration of a predefined time interval or a predefined number of simulation steps, is met.
- a predefined condition e.g. the expiration of a predefined time interval or a predefined number of simulation steps.
- the first type of exchange values 36 with corresponding mirrored values 36.M is used in the direction from the higher-level function 32 towards the programmable gate arrangement 10.
- the second type of exchange values 36 with corresponding mirrored values 36.M is used in the direction from the programmable gate arrangement 10 to the higher-level function 32. This is indicated in Figure 1 by arrows in two directions between the exchange values 36 and the driver 20.D of the monitoring circuit 20.
- the driver 20.D therefore stores mirrored values 36.M which are intended for exchange with the monitoring circuit 20 of the programmable gate arrangement 10.
- the mirroring of the values between the exchange value range 36 and the mirrored values 36.M can be implemented in various ways.
- One possibility involves the variable with the exchange value 36 of the higher-level function 32 being used directly by the driver 20.D as the mirrored value 36.M.
- Another possibility involves both the exchange value 36 and the mirrored value 36.M being present and both values 36 and 36.M being written during write operations.
- a preferred further possibility involves both values 36 and 36.M being present but pointing to the same memory locations on the processor board.
- the driver 20.D has a further interface DAQS.
- a data exchange DAQ with the operating unit 50 can take place via this interface DAQS to the operating unit 50.
- the interface DAQS can receive and store information ML about values to be recorded from the operating unit 50 via the interface DAQ.
- the values received from the driver 20.D can be temporarily stored in the buffer MB of the interface DAQS and the values from the buffer MB can be transferred to the operating unit 50 via data exchange DAQ.
- the programmable gate arrangement 10 is set up to execute a function 22.
- the function 22 has a data exchange with the higher-level function 32. This data exchange within the scope of the execution of the function 22 and the higher-level function 32 is not shown in Figure 1.
- signals Sl are exchanged which are generated during the execution of the Function 22 can be used by function 22.
- Function 22 can also be set up to change the value of signals S1, to receive the value of signals S1 from higher-level function 32 and/or to process the values of signals S1 and to output values derived from signals S1 back to higher-level function 32.
- Signals of function 22 can also be designed as constants Kl. Function 22 is able to use and process constants Kl.
- the programmable gate arrangement 10 has input/output interfaces IO. Via these input/output interfaces IO, for example, sensor values can be read in or values can be output by the programmable gate arrangement 10.
- the input/output interface IO can be an analog interface, for example.
- the gate arrangement can, for example, calculate values of signals S1 from sensor values.
- the signals S1 of the function 22, which can also include constants Kl, can be accessed by the monitoring circuit 20 independently of the execution of the function 22.
- the monitoring circuit 20 can read signals S1 and/or write constants Kl.
- the monitoring circuit 20 is controlled by the driver 20.D of the processor 30.
- the monitoring circuit 20 can be informed by means of commands CMD which signals S1 should be read out and/or which constants Kl should be modified.
- the values of the signals S1 and/or the constants Kl can then be transferred from the monitoring circuit 20 to the driver 20.D via the read values RV.
- Contents of the commands CMD can, for example, have mirrored values 36.M.
- the read values RV can be stored in the mirrored values 36.M.
- the higher-level function 32 can write values via the exchange values 36 using the driver 20. D into the mirrored values 36. M values, which are then transmitted to the monitoring circuit 20.
- the transmitted commands CMD can include information about which signals S1 should be read out by the monitoring circuit 20 and/or which constants Kl should be rewritten with which values.
- Figure 1 indicates that a processor 30 can interact with several programmable gate arrangements 10.
- the higher-level function 32 can incorporate a function 22 of a programmable gate arrangement 10 into its execution. It is also possible for further functions of further gate arrangements to be incorporated into the execution of the higher-level function 32. This is indicated in Figure 1 by further gate arrangements.
- the programmable gate arrangement 10 there is an interface environment IS, which in particular has the monitoring circuit 20 and memories of the function 22, which include those memories where, for example, the signals S1 are provided for reading by the monitoring circuit 20. Such memories are also referred to as shadow registers.
- the interface environment IS can also have the memories that store the constants Kl.
- the operating unit 50 has, for example, a screen area 52.
- An input unit 54 can be provided in the screen area, which is designed to accept inputs from a user.
- the input unit 54 can be designed, for example, as a touch-sensitive screen. Other input methods are conceivable, for example via a keyboard, mouse or others.
- the screen area 52 also has an output unit 56, via which values 58 can be output.
- a data exchange DAQ via the interface DAQS of the processor 30 is provided for the operating unit 50.
- signals S1 of the gate arrangement can be accessed via the monitoring circuit 20 both by the higher-level function 32 of the processor and by a user via the operating unit 50.
- the monitoring circuit 20 is designed such that the exchange of the signals Sl, including the constants Kl, takes place without interfering with the sequence of the function 22.
- the implementation of the monitoring circuit 20 is designed such that it is independent of the function 22 on the programmable gate arrangement 10. This is achieved in particular by storing values of signals Sl in so-called shadow registers. The values of the signals Sl are stored in these shadow registers, from where they can then be fetched by the monitoring circuit 20. The fetching does not influence the sequence of the function 22, but takes place independently of it.
- Figure 2 shows an example of how signals Sl of function 22 within higher-level function 32 can be accessed via monitoring circuit 20.
- Figure 2 shows example data for this purpose, as it may be present in a simulation model of higher-level function 32.
- the example data in Figure 2 is initially a single value in the top line.
- the second line of Figure 2 shows an example of a vector.
- the third line of Figure 2 shows an example of a matrix.
- the fourth line of Figure 2 shows an example of a bus.
- This data can be present in the simulation model of higher-level function 32 in the form shown. In order to identify this data as exchange values 36, it can be specially identified in the naming, for example. This could be done, for example, by a prefix that is placed in front of the variable name.
- the values shown from the exchange value range 36 are mirrored into the mirrored range of the mirrored values 36.M of the driver 20.D. In the area of the mirrored values 36.M, these are regularly updated via the monitoring circuit 20. The updated values 36M are mirrored in the area of the exchange values 36 via the driver 20.D. This allows the exchange values 36 present in the simulation model of the higher-level function 32 to be updated via the driver 20.D and the monitoring circuit 20, so that the exchange values 36 are present in the higher-level function, as they are currently present in the gate arrangement 10 as signals Sl, optionally comprising the constants Kl.
- Figure 3 shows an example of the other direction of data exchange.
- the first line of Figure 3 shows a simple variable
- the second line of Figure 3 shows a vector
- the third line of Figure 3 shows a matrix
- the fourth line of Figure 3 shows a data bus.
- these values are shown in the simulation model of the higher-level function 32, for example as a data sink. It is also possible to choose a different format to symbolize that a value is to be written.
- Write operations are carried out in the area of the mirrored values 36.M via the area of the exchange values 36.
- the values 36.M in the form of mirrored values are then written into the memory of the gate arrangement 10 via the monitoring circuit 20.
- Figure 4 also shows examples of data sinks that can occur in the simulation model of the higher-level function 32. Again, they are shown in this order: simple variable, vector, matrix, data bus.
- the values shown in Figure 4 also have a validity signal "Enbl", technically referred to as an "enable signal” Enbl, which can be applied to a validity signal input En-in, technically referred to as an "enable port” En-in.
- the respective enable port En-in shown is an assigned control input for the respective assigned data sink, which signals to a corresponding signal input Dt-in of the data sink that the value present at the signal input Dt-in is either valid or not.
- a positive logic or a negative logic can be specified for the enable port En-in.
- a signal present at the signal input of the data sink is only to be considered valid if there is a positive voltage level with a predefined voltage amount present at the enable port En-in of the data sink, i.e. a validation signal Enbl is present.
- a typical application for a large constant Kl is, for example, that an engine characteristics map of an engine to be simulated by the higher-level function 32 and the function 22 is to be stored as a constant Kl.
- This large amount of memory can, for example, be stored in several memory areas 60 ( Figure 5), e.g. B. BlockRAM blocks, abbreviated to "BlockRAM".
- Figure 5 e.g. B. BlockRAM blocks, abbreviated to "BlockRAM”.
- BlockRAM BlockRAM blocks
- Figure 5 shows an example of the gate arrangement 10 with several memory areas 60. These memory areas 60 are, for example, the aforementioned BlockRAM of the programmable gate arrangement 10, for example of an FPGA.
- Such a memory area 60 is characterized in that it can be addressed by configuration bits and data bits.
- the configuration bits define where in the memory area 60 the data bits are to be stored.
- At least one parallel interface is provided for access to the memory areas 60. In the example shown, two parallel interfaces are provided, one for writing and one for reading. The configuration bits and the data bits are exchanged in parallel with the memory area 60 via the parallel interfaces.
- the illustrated parallel interface between a deserializer “Des” or a serializer “Ser” and a connected memory area 60 is generally not disadvantageous if the deserializer or serializer is arranged close to the memory area 60.
- the configuration bits and the data bits must be transmitted from the monitoring circuit 20 to the memory area 60 and read data must be transmitted from the memory area 60 to the monitoring circuit 20. This is necessary, for example, if signals Sl stored in the memory area 60, for example constants Kl, are to be read and/or written by the monitoring circuit 20.
- the memory arrangement 23 has deserializers Des and serializers Ser in addition to the memory areas 60.
- One deserializer Des is provided for each memory area 60.
- One serializer Ser is provided for each memory area 60.
- the deserializer Des of the memory area 60 has the task of receiving the configuration bits and the data bits in serial form, parallelizing them and transmitting them to the memory area 60 via the parallel interface.
- the serializer Ser has the task of receiving and serializing parallel data, i.e. the configuration bits and the data bits from the memory area 60 in parallel form.
- a converter 24 is provided for communication between monitoring circuit 20 and memory arrangement 23.
- Converter 24 has a serializer Ser and a demultiplexer Demux.
- Converter 24 also has a deserializer Des and a multiplexer Mux.
- the serializer Ser of the converter 24 has the task of serializing parallel data output by the monitoring circuit 20, for example parallel configuration bits and data bits for one of the memory areas 60.
- the serialized data bits and configuration bits are assigned to the specific memory area 60 via the demultiplexer Demux and transmitted via a serial data line to the respective deserializer Des of the memory arrangement 23 assigned to the specific memory area 60.
- the monitoring circuit 20 receives parallel data from the deserializer Des of the converter 24.
- This parallel data was composed of serial data by the deserializer Des of the converter 24.
- This multiplexer Mux is able to receive the serial data bits and configuration bits of the respective memory areas 60 and to switch between these memory areas. In the embodiment of Figure 5, it is preferred that the multiplexer Mux receives the serial configuration bits and data bits from the respective serializer Ser assigned to the corresponding memory area 60.
