Example 1

Fig. 1 is a flowchart of a method for verifying a network on chip NOC according to an embodiment of the present invention, where the method may be performed by a device for verifying a network on chip NOC, and the device may be implemented in hardware and/or software. As shown in fig. 1, the method includes:

step S101, channel data of a designated interface in the NOC are obtained through the interface agent, and the channel data are sent to the data forwarding component.

Specifically, as shown in fig. 2, a schematic diagram of a NOC verification environment provided in this embodiment includes a data forwarding component Refmodel, a static configuration component glb_sel_cfg, and a plurality of interface agents connected to the data forwarding component. The interface agent comprises a node interface agent and a cross interface agent, the node interface agent comprises three Master IP cores Master VIP and one Slave IP core Slave VIP, and the cross interface agent comprises two Slave IP cores Slave VIP. The Master IP core Master VIP is connected with the Master interface NIU-M of the NOC, the Slave IP core Slave VIP is connected with the Slave interface NIU-S of the NOC, each appointed interface is connected with a node in the NOC, and the node in the NOC can be a Slave node or a Mster node. The agents in this embodiment are all nodes corresponding to each other in the NOC network, and the nodes corresponding to the agents are not limited in this embodiment. In addition, in the excitation application mode of the verification environment in this embodiment, the Master VIP of each agent applies test sequence sequences of various transmission types to initiate transmission to each Slave node, and the VIP of each Slave node replies with various responses.

Optionally, the interface agent further includes a monitoring component that obtains channel data of a specified interface in the NOC through the interface agent, including: acquiring control data channel data and response channel data in a main interface through a monitoring component; control data channel data and response channel data in the slave interface are acquired through the monitoring component, wherein the control data channel data comprises write address channel data, read address channel data and write data channel, and the response channel data comprises write response channel data and read data channel data.

The system comprises an interface agent, a monitoring component Monitor, a control data channel and a response channel, wherein the monitoring component Monitor is also included in each interface agent, and the transmission of an AXI port detected by the Monitor of an AXI Master/Slave of NIU-M and NIU-S is used as a source for verifying environment data comparison, and is divided into two types of control data channels and response channels for signal detection and data comparison. In the signal detection, the control data channel data and the response channel data in the master interface NIU-M are acquired by the monitoring component in the embodiment, and the control data channel data and the response channel data in the slave interface NIU-S are also acquired by the monitoring component. Wherein, the control and data channels refer to a write address channel AW, a read address channel AR and a write address channel WDATA of an AXI protocol; the response channels refer to the write response channel B and the read data channel R of the AXI protocol. And each interface agent, after acquiring channel data in the master interface NIU-M or the slave interface NIU-S, sends the channel data to the data forwarding component Refmodel.

Optionally, before sending the channel data to the data forwarding component, the method further includes: comparing the control data channel data in the master interface and the slave interface through the monitoring component; the response channel data in the master interface and the slave interface are compared by the monitoring component.

In one specific implementation, the monitor component Monier also performs data comparison on the channel data before sending the channel data to the forwarding component, and one direction of data comparison is a control data channel, and the other direction is a response channel. For example, for the control data channel direction, the Monitor collects the control data channel data of the interface NIU-M in the NOC, and compares the signal collected by the interface NIU-M with the signal collected by the interface NIU-S. In addition, aiming at the response channel direction, the Monitor collects the response channel data of the NIU-S interface, collects the response channel data of the NIU-M interface in the NOC, and compares the signal collected by the NIU-M interface with the signal collected by the NIU-S interface.

Step S102, the data forwarding component obtains the target address in the channel data and forwards the channel data to the target interface agent matched with the target address.

Optionally, the data forwarding component includes a switching unit, forwards the channel data to a target interface agent matched with the target address, including: the target slave node in the NOC is obtained through the switching unit according to the mapping of the target address; determining an interface agent matched with the target slave node, taking the matched interface agent as a target interface agent, and forwarding channel data to the target interface agent.

In this embodiment, the NOC network performs data routing transmission, and the same data transmission process is also required in the verification environment of the NOC. The two are the same principle, but are not identical where the NOC is designed to send and receive Master and Slave nodes, while the verification environment is to perform the same tasks in the data forwarding component Refmodel, but the sender and receiver become the interface agent. The core function of the Refmodel is to design a switch unit, route the target address range to the target slave according to the need of following in the verification environment, and send the monitor data to the corresponding agent according to the route target. That is, after the target address in the channel data is obtained, the target slave node is obtained through address mapping, and as the nodes in the NOC all have corresponding agents in the verification environment, the target agents matched with the target slave node can be obtained, and the data is forwarded to the target agents through the switch, so that the consistency of the verification environment and the data transmission process in the NOC is ensured.

And step S103, closing the designated interface agent corresponding to the designated node which does not participate in transmission access in the NOC through the static configuration component, and performing null processing on the designated node and the designated interface agent.

Specifically, the static configuration component in this embodiment has a function of selecting the positions of the master node master and the slave node slave that need to be used in the test case simulation, and configuring the position coordinates as global parameters in each level of the verification environment. And determining whether to open the node interface agent in the verification environment according to the selection configuration, and closing the designated interface agent corresponding to the designated node for the nodes which are not in the source and destination of the access, namely the designated nodes which are not involved in the transmission access in the NOC.

Optionally, the designated node includes an external router and an internal router, and the processing of the designated node and the designated interface agent to make a null includes: making the internal router in the appointed node empty; the designated interface agent is excluded from the NOC verification environment.

It should be noted that, due to the huge NOC network scale, the consumption of the simulation resources and time for the entire design scale will be very large, and in order to flexibly optimize the scene requirements of various test cases, the design and verification environments need to be flexibly adapted to do the blank processing. For NOCs, the node is designated not to participate in the transmission access, its internal router is left empty, while the external router of that node is reserved. The node_agen corresponding to the designated node is excluded from the verification environment. After each unnecessary node is emptied through the operation, the corresponding following resources in the verification environment can be saved, firstly, the instantiation of the unused node agent can be removed, and secondly, the signal connection between the IP core in the agent and the design NOC can be removed. Therefore, only the transmission node in the verification environment needs to be hung with the corresponding agent through the emptying processing, if the transmitted scene only needs few nodes, the resource cost of the verification environment can be greatly reduced, and the simulation efficiency is improved.

The embodiment of the invention sends the channel data of the designated interface in the NOC to the data forwarding component through the interface agent, and the data forwarding component forwards the channel data to the corresponding target interface agent so as to realize the verification of the NOC, and the designated interface agent which does not participate in transmission access is closed and idle through the static configuration component, so that the resources occupied in the NOC verification process are saved, and the NOC verification efficiency is improved.

Example two

Fig. 3 is a flowchart of a network on chip NOC verification method according to a second embodiment of the present invention, where the method further includes detecting an interface agent in a NOC verification environment after performing a null processing on a designated node and the designated interface agent based on the above embodiment.

Step S201, channel data of a designated interface in the NOC is obtained through the interface agent, and the channel data is sent to the data forwarding component.

Step S202, the data forwarding component obtains the target address in the channel data and forwards the channel data to the target interface agent matched with the target address.

And step S203, closing the designated interface agent corresponding to the designated node which does not participate in transmission access in the NOC through the static configuration component, and performing null processing on the designated node and the designated interface agent.

Step S204, detecting an interface agent in the NOC verification environment.

Specifically, when the designated interface agent performs the idle processing, the designated interface needs to be excluded from the verification environment, and since the original number of the interface agents in the verification environment is known, the agents in the NOC verification environment are detected after the idle processing is performed, so as to see whether the current agents are the same with respect to the original number. If the operation is not the same, the operation is indicated to be effectively executed, and if the operation is the same, the operation is indicated to be not effectively executed. And prompt information is sent to the user under the condition that the idle processing operation is not effectively executed, so that the user can know the specific flow of the verification process in time, and the invalid processing operation is correspondingly adjusted.

The embodiment of the invention sends the channel data of the designated interface in the NOC to the data forwarding component through the interface agent, and the data forwarding component forwards the channel data to the corresponding target interface agent so as to realize the verification of the NOC, and the designated interface agent which does not participate in transmission access is closed and idle through the static configuration component, so that the resources occupied in the NOC verification process are saved, and the NOC verification efficiency is improved. And under the condition that the idle processing operation is not effectively executed, prompt information is sent to the user, so that the user can know the specific flow of the verification process in time, and the invalid processing operation is correspondingly adjusted.
