Adding gds number to LSW display

jaleco

Is there a way to add layer gds stream numbers (extracted from the techfile with the lpp) to the LSW display?

I am using v5.1.41

    I'm not saying it isn't useful now and again, but I doubt most people would want to see it all the time (I was one of the AE's who requested this being added into the IC615 layer palette on behalf of a customer). I just thought that having to go through convoluted routes to display it in IC5141 when you'd end up having to see it all the time (I guess you could change the techfile in memory only) seemed overkill to me.

    I'm quite happy to be wrong though - If you think it's worthwhile, that's fine!

    Hi Andrew, 

    I am trying to load the GDS numbers, in the LSW in IC618. It would be very helpful when making a release for tape-out and verifying job-deck. I dump the tech file with only layer and purpose definition and try to load it; doesn't work. Second,  I notice that the CAD no. (Mask ID) are different from the layers numbers defined in TechFile. I am actually interested in loading tsmc Mask ID in LSW.  Do we need to make a separate file with the layer and Mask number defined. Are we still have to follow what some users explained for modifying abbreviations in tech file etc. to get the number displayed in LSW.  Appreciate if you could explain the steps to a little in detail. Well, I am working on modifying LSW for the first time. Thanks.

    The stream (GDS) layer numbers/datatype numbers are found from the libName.layermap file found within the technology library you're using - this is the same file that seeds the File->Export->Stream interface too. The stream layer/datatype numbers are not in the tech file (they were in CDB releases like IC5141, but in OpenAccess this is not part of the  OA technology database, but is a separate file)

    You can enable them in the Layer Palette using the Right Mouse button menu as follows:
