Concept of Co-Verification . . .

Software development and debug , performed on (almost) freezed RTL rather than on the first silicon

Efficient reduction in the time to market delay of the product

Scope to fix system level bugs in HW, rather than as a SW patch

Respins efficiently avoided

System performance measured at very early design stage

Co-Verification for SoC Designs

Co-verification is a productive approach to minimise the overall product development turn-around time. Some significant advantages for SoCDesign are as listed below

Co-verification is helpful for “Application Usecaseverification”

Co-verification environment can also be used for system stress testing

Emulation supports co-verification and has good EDA support

Conclusion . . .

Co-verification is helpful to tackle growing SOC Design complexity and associated SW development , thereby reducing the time-to-market delays.

Co-verification can be used for “Application UsecaseVerification” which is now significant part of SoC Verification process.

Emulation can be used as a vehicle for hardware/software co-verification – supporting real world data for comprehensive system testing, and a complete software debugging environment.

Summary . . .

Software content of electronic products is increasing exponentially and is most often the pacing item for product completion. Software simulation alone is not fast enough to test the volume of software being written for today's electronic products. Using acceleration and emulation for hardware/software co-verification takes advantage of the investment made in the emulator for SoC verification to speed software debugging thus shortening product cycles by several months.
