Hello, I'm trying to do accurate power analysis via xpower.
I'm using ISE P.20131013. and xpwr: Release 14.7 P.20131013 (lin64)
So I have my core module, which I synthesize. I wrap it in testbench, run simulation and dump vcd file via commands:
vcd dumpfile ..
vcd dumpvars -m /testbench/my_core/
then I turn off simulation tool and launch XPower via:
xpwr -s myvcd.vcd data.ncd data.pcf
but I get following errors:
WARNING:Power:216 - VCDFile(18970): $dumpoff command encountered, all simulation data after this will be ignored. ERROR:Power:972 - Parsing Error parse error, unexpected WORD, expecting END or TRANSITION or BINARY_VALUE or REAL_VALUE line 18973 Expected scalar or vector value change here ERROR:Power:85 - Error reading VCD file, no simulation data will be applied. WARNING:PowerEstimator:270 - Power estimate is considered inaccurate. To see details, generate an advanced report with the "-v" switch.
Number of error messages: 2 Number of warning messages: 2 Number of info messages: 1
on 18973 line in vcd file there is:
1! #3599000 0! #3600000 $dumpoff x! x" x # << this one x $ x % x &
