My university is trying to sort out the Silicon ensemble and buildgates software packages, the requirement is to do timed simulation of a standard cell library but iam not sure how to do this. Build gates will synthesize the design from vhdl and silicon ensemble will convert the design to gds2. Now I want to do a timed analysis, originally the plan was to use modelsim with an .sdf file format however that would involve writting sdf files for the standard cell library which I have (Virtual Silicon 0.18um Library, UMC).
 

SE can export SDF file for your time analysis also.

When you do synthesis with BG, you should read the lib to your netlist. Then you can use the command "write_sdf" to write the timing sdf file. Annotate this sdf in your netlist, then do pre-simulation with ModelSim.

After using SE, you can product a sdf file including the wire-delay model. With the same way to do post-simulation.

Certainly, those ways is dynamic timing analysis. You should do STA for complete timing analysis.

Good Luck
 

Thanks I will give these suggestions a go and see what happens.
