VPR Graphics

[Saeede Askari]

Hi,

I was following the Quick Start Guide in vpr documentation and I was trying to enable the graphics so I installed the dependencies and built the vtr again. Now I am not able to run it, facing this error:

Error 1: tseng.net:-1 Failed to open file

What is the problem and why does the netlist fail to open?

That error is unrelated to the graphics.  It means the tseng.net (and output file from packing) could not be opened.  Probably this means you don't have write permission in the directory in which you are running vpr.  If you cd to a directory to which you have write permissions before invoking vpr it should work.  Alternatively you could specify the 

--outfile_prefix <somepath> 

option to direct the output files to some convenient directory to which you have write permission.
