Simulation and verification of a mixed-signal programmable system-on-a-chip

An overview of a simulation strategy for the verification of one of the first mixed-signal field-programmable system on a chip (FPSOC) is presented. The FPSOC integrates a microcontroller, FLASH memory, programmable digital blocks, and programmable analog blocks. A proprietary digital Verilog with analog extensions was used to verify system interactions between the analog and digital blocks. A first-pass functional silicon was obtained because of the simulation methodology.
