HI
i have a serious problem with power estimation in PKS.I read in "Low Power Option for Ambit buildgates and...." reference that to estimation of power in PKS i must have a tcf file,so with much trouble i could generate a VCD file using Modelsim-Altera and converted it to tcf file using pksvcd2tcf.exe from PKS.here are both of them.but when i tried to estimate power as in low power option reference for LPS-PKS in page 100, i received following lines after reading tcf file in PKS show that there is no switching activity in my design!!!!!!!!!!!!!!!
pks_shell[25]>read_tcf /home/mostafa/SOC/BuildGates/v05.13/bin/linux/x86/transmitter.vcd.tcf_hier
Info: In the current module,
0.00% of nets have asserted signal probability
0.00% of nets have asserted transition count
0.00% of primary inputs and outputs of sequential elements
have asserted signal probability
0.00% of primary inputs and outputs of sequential elements
have asserted transition count <PA-260>.
i think the problem is with pksvcd2tcf.exe!!so can anyone suggest me another flow to estimating power or a way to convert vcd file to tcf file??
and if i don't read a tcf file for power estimation the power that PKS gives is true???
please someone heeeeeeeeeelp me.
thank you
