Error with getAsciiWave() in Cadence Virtuoso

intern

I tried the command: plot(getAsciiWave("test.txt" 1 2)) however I get the following error:

"File /filepath/ is not readable. In order to proceed with creation of waveform object ensure that the specified file is in readable mode."

I have a text file with two large columns of data, and I want to be able to plot the data in ViVa and then plot the results of my simulation to compare the graphs.

Any help will be appreciated.

Thanks.  

  • First thing to check is that the file actually exists and is readable. Note that getAsciiFile() will use the normal SKILL mechanism of reading files without a directory using the SKILL path - so check in the CIW what:

    getSkillPath()

    returns. Does it include "." in the list? If not, it means it won't be looking in the working directory for files, and that might be why it doesn't find it. You could solve that two ways - either:

    1. setSkillPath(cons("." getSkillPath()))
    2. or change the fileName in the getAsciiWave() call to "./test.txt"

    Regards,

    Andrew.

  • Thanks Andrew, your solution worked. I appreciate the help.
