Method of designing semiconductor integrated circuit device |
摘要 |
A system which allows signal transmission between circuit blocks is constructed promptly by automatically generating an I/F circuit in response to the adjustment of a timing relationship and to a modification in a waveform on a GUI and automatically inserting the I/F circuit between the circuit blocks or adding the I/F circuit to any of the circuit block. A circuit for outputting an operation enable for a receiving side is generated automatically between a plurality of blocks operating with different frequencies, whereby the use of the circuit blocks is expanded in spite of the different frequencies. Further, the design of a large-scale system is performed efficiently by automatically generating a desired waveform by a simple editing operation, generating a desired signal waveform by forming a combinational circuit of signals in the circuit block, and automatically generating a logic synthesis script.
