I am trying to generate power report using Synopsys DC compiler.

At first I have generated VCD file using Modelsim simulator, which I have converted to SAIF file using "vcd2saif" command. Then I proceeded to analyze the power through DC compiler.

However, I am getting an warning " There are 1166 objects not found during annotation", and the combinational switching power is showing zero for my design.

What can be the error?

I believe the internal signals in the generated SAIF file from the MODELSIM does not match with the internal signals of the synthesized netlist. Do I have to perform postsynthesis simulation, but then how to link the design library file with MODELSIM.

Kindly guide in this regard.

  • \$\begingroup\$ To update, I tried postsynthesis simulation using lib.v files corresponding to synthesis library. However, the size of vcd file now being generated is too large. \$\endgroup\$ – avi1987 Aug 28 '19 at 20:24
