Error in Cadence RTL Compiler when estimating Power using VCD

RileyDylan
RileyDylan over 4 years ago

Hi, 

I want to estimate the power using a VCD I dump directly from my testbench. The commands I use for dumping the VCD are:

$dumpfile("OneExample.vcd");
$dumpvars(0, Top_tb.CyNAPSE);
(testbench file is Top_tb and the module instantiated in it is CyNAPSE of type Top. Top is the top module included in the synthesizable RTL)
I use the following Cadence RTL compiler command in my synthesis script (after elaborate and before synthesize)
read_vcd -vcd_module Top_tb -module Top -static ../rtl/OneExample.vcd
I receive the following error: 
Error : Syntax error in input VCD file. [POPT-550] [lp_new_vcd_analysis]
         : syntax error at line number 8146609 in file ../rtl/OneExample.vcd

         : Correct the error at indicated line number.
(line 8146609 is the last line of the .vcd file)
I have included the testbench file Top_tb.v as well as synthesizable top module Top.v in the read location for the tool to find (../rtl/). 
Can anyone help me with this? I will greatly appreciate it.
Thank you!
