  • using ModelSim/QuestaSim VCD file in RTL compiler

    Hi, I want to use VCD file from QuestaSim 6.0 in RTL compiler to obtain power report. The netlist file I am using in QuestaSim for simulation and VCD file generation is also generated by RTL compiler byt when I run following commands I got no asserted signals in the power result. Does RTL compiler supports...

  • NCSIM: problem with vcd filesize limit

    Hi, I'm currently working with a vhdl example to check the ability of ncsim to limit the filesize of vcd dumpfiles. For that I set up a simple mux with a testbench, that generates stimuli over 540ms. The following simulation flow results in a 1,7G VCD file: $ ncvhdl -cdslib ./cds.lib -hdlvar ./hdl...
