Assura LVS / generate labels from pin names

Hi all,

My Assura LVS is not able to see the pins because there are no labels
assigned to it.
So, is there a way to generate these labels for the respective pin
names for the whole design.
Or provide a list to assura informing the tool that these are pins.

Thanking You,

Cheers
Dinac

 

Hi Dinac - Assura uses pins when running DFII and uses labels based on
their origins when running GDS. There are
skill routines that will generate pins from labels and labels from
pins. Are you running DFII or GDS?

Hi Rick, Thanks for your reply.I am using DFII.
There are pins in my design. But Assura gives match only after placing
the label to the respective pins.
So I need to generate these labels for all the pins in my design.
If I am right, 'pinTextFile ' could do this?? But i am searching for a
format of this file.

Thanks

cheers

Hi Dinac - you could a few things going on here:

1) the pins have lost their connectivity
2) the deck is setup to only recognize text and not pins.
3) the pins are not on the correct layer

What does the .erc file show, does it report any pins? The pinText
file will work but it can be
a huge task to manually generate if you have a bunch of pins. The
syntax is:

name x-coord y-coord ATTACH=<layerName>

VSS_ch3 60.21 -33.630 ATTACH=met3

BTW, most decks will use lower case even if the techFile is upper case
but it can go either way.
Sourcelink has a skill routine that will generate labels from pins:
