Definitions
- a hard macro block such as the hard IP module also includes information on a mask pattern for forming a verified late pattern as a data provided to a designer. Therefore, the circuit characteristics of blocks (circuits) provided as hard IP modules are guaranteed. Therefore, when designing microcomputers and system LSIs, the use of hard macro blocks such as hard IP modules, which are past design assets, can greatly reduce the design and verification period. Can be.
- the function description by HDL etc. included in the hard IP module is used to verify the logical operation etc. of the integrated configuration of the hard IP module and the outside when the hard IP module is connected to the outside .
- the present inventor described the above-mentioned hard IP module software in designing a semiconductor integrated circuit.
- G The use of data such as IP modules was examined.
- micro-computers can be deployed as products by adding peripheral functions that meet the specifications required by users to the CPU that is the core of micro-computers.
- the already designed hard IP module is reused as a peripheral circuit module to shorten the design period, the design period up to the layout can be reduced as described above.
- Still another object of the present invention is to provide a storage medium storing design data enabling reduction of power consumption and / or chip occupation area of a reusable module in a semiconductor integrated circuit. .
- FIG. 12 is an explanatory diagram showing an example in which the first circuit in FIG. 10 is a hard module, the second circuit is a soft module, and each is composed of separate IP modules.
- the second circuit 3 is an interface circuit or buffer circuit such as an address output register, a data input / output register, a control signal flip-flop, and a logic gate.
- the second circuit 3 includes a two-input OR gate 30, a two-input AND gate 31, an invar 32, and a buffer 33.
- PS 1 N and PS 3 N are representative input signals external to the module
- RXIN and ERIN are representative output signals external to the module.
- nl to n6 exemplify net names in the second circuit 3
- N1 to N6 exemplify terminal names in the first circuit 2.
- FIG. 2 shows data (hereinafter referred to as I
- the computer decodes the data and performs processing.
- the computer executes a specific program in order to decode and perform the processing.
- the computer may be a distributed processing system. For example, each of the disk access, the layout calculation, and the man-machine interface may be processed using a separate computer, and the processing results may be used in cooperation. If the capacity of the IP module data including the first to third data DTIDT 1 to DT 3 becomes large and cannot be stored in one storage medium 44, a plurality of The IP module may be stored over a storage medium. Of course, the IP module data may be divided in advance so as to be stored in a plurality of storage media, and may be stored in a plurality of storage media.
- Step S1B when designing the semiconductor integrated circuit, even when the external load of the above-mentioned inverter 32 is small, the second data DT 2 loaded on the computer as shown by 51 and the second data DT 2 shown by 50B Then, the result is logically synthesized (Step S1B). However, in this case, since the external load of the above-mentioned room 32 is determined to be relatively small from 50 B on the day, the second data that is loaded on the display is 52 B The description is modified so that the inverter 32 of the second circuit 3 employs the inverter INV-S having a small driving capability, as shown in FIG.
- DT4 which is the fourth day for Noh. Since the terminal of the first circuit 2 serves as a connection terminal with the second circuit 3, the fourth data DT 4 From the second circuit 3, the characteristic or / and the logic function at the terminal of the first circuit 2 can be grasped as data for making it visible.
- only the third information may be stored in a storage medium and provided.
