deepprobe node name for extracted netlist

Karev11

Hi,

I'm trying to use deepprobe to access internal node of an extracted block.  My netlist is from Star-RC extraction and has default node name format as below:

Q2

Q2:1

I113/MMP0:G

...

the top level is called Itop, so far I only had success in below:

Itop.Q2

and below doesn't seem to work:

Itop.Q2\:1

Itop.I113\|MMP0\:G

I also try to replace colon with underscore in the netlist file (Q2:1 ->  Q2_1), but below still doesn't work

Itop.Q2_1

Any comment on what is wrong with my syntax?

thanks,

Kevin

  • Hi Kevin,

    The right names would be:

    • Itop.Q2\:1
    • Itop.I113\/MMP0\:G

    The forward slashes and colons need to be escaped (if you leave the colon unescaped then this is illegal syntax in Spectre). Unfortunately it seems that one of the options that ADE passes to spectre interferes with the handling of colons, and that is a bit of a problem... it sees the escaped names as above as unconnected.

    There are two choices here:

    1. Substitute all the colons in the included file to be something else (e.g.underscore).
    2. Add -escchars to the User Command Line Options field on Setup->Environment in ADE

    The first is probably my preference; whilst the second works, I'm not entirely sure what it might break by turning "escchars".

    Also just realised that this came up a while ago in this post (I hadn't come up with the -escchars trick then though).
