Abstract
A method for efficiently changing the embedded processor type in verification of system-on-chip (SOC) integrated circuit designs containing embedded processors. The verification software is used to generate and apply test cases to stimulate components of a SOC design ('cores') in simulation; the results are observed and used to de-bug the design. Typically, the embedded processor type changes as SOC designs change. However, changing the processor type may cause errors in verification due to the presence of processor-specific code distributed throughout the verification software. Thus, changing the processor type can entail a substantial re-write of the verification software. In the method according to the present invention, in verification software for verifying a SOC design including an embedded processor, processor-specific code is localized in a processor driver. Consequently, when there is a need to change the processor type, only the processor driver needs to be changed or replaced, while the rest of verification code requires no changes. Verification is consequently more efficient.
