SDF Errors

tswong

We are performing postlayout simulation for a digital design which adopts TSMC 65nm standard cell library. During SDF back annotation by Verilog-XL 8.2, there are many SDFA errors, "Failed to find SETUP timingcheck" and "Failed to find HOLD timingcheck". But the simulation is still passed. Is it caused by mismatch Verilog model of the standard cells? or by improper EDA tools? Is it important?

Thanks!
