How to become a senior digital IC Design Engineer (6-6) digital IC Verification: system level simulation

One 、 Sort by stage

1、 Before the imitation

        Means according to Intermediate version 、 The final version of RTL Code Conduct function Validation on .

2、 Post imitation

        Means according to Intermediate version 、 The final version of Netlist、SDF（ belt Power Or not Power） And so on 、 Functional simulation 、 Power consumption simulation 、PG Simulation .

        1、 Functional simulation ： Mainly determine whether the function is correct ,IO Whether the timing constraint OK;

        2、 Power consumption simulation ： It mainly determines whether the power consumption of each module meets the expectation , Whether the specification requirements are met ;

        3、PG   Simulation ： Mainly determine whether the low-power design process is normal ,Power Whether the interface is clean , Whether the special signal processing is in accordance with the requirements .

Two 、 Sort by way

         It is mainly divided into UT、IT、ST;

        ST： According to the real CPU Behavior configuration related registers , Data processing , adopt C The code compiles HEX file , then LOAD To... In the system RAM/SDRAM in , Release CPU Reset , Make it read and execute RAM/SDRAM Instructions and data in , After the simulation , see LOG/MEM_COMPARE/TXT/WAVE, confirm CASE Whether it ends normally ;

         The simulation system flow is for reference only , There are many details in the system simulation of the actual project , To be confirmed at that time .
