OSSHNL ERROR 514 and 287

PeteK

Hi, I am designing a datapath circuit, but I am having trouble with cadence software virtuoso &

My circuit can't netlist, but sometimes it does netlist after a few hours, even if nothing got changed in between. Sometimes i select 'escape names', and it netlists, other times it doesn't even if i select it or delete the run folder. Netlisting has completely become random for me, yet it was working fine a week ago, the errors below are the ones output when it fails;

  • First of all, you didn't mention which netlister you're using (I'm assuming it's the NC Verilog integration), and also you didn't mention the version.

    However, I think the error message is pretty clear. You have hnlMaxNameLength set too short. The default value of this variable is 50, but you have it set to 16.

    You can add:

    hnlMaxNameLength=50

    in a .simrc file (e.g. in the working dir), or you could just try typing that in the CIW.

    That should fix it. I saw a similar problem in the version I was using when I set hnlMaxNameLength too short. The escaped names is a piece of generic advice - it probably doesn't help in general in this case.

    Also, it's usually better to post the text of the error message rather than a link to a picture of the error message. It's pretty hard to search a picture... so if anyone else hits this issue in the future, it's unlikely they'll find this post.

    Regards,

    Andrew.

  • Thankyou very much Mr. Andrew, it worked, i changed it in the .simrc file
