Techgen Error: Starting Triangle not defined

HI all,

I am trying to generate a qrcTechFile using Techgen and my own ICT file. However, I have run into a problem. My first question is whether I am running Techgen correctly (I have never worked with Cadence before). I try to run the Techgen simulation with my ICT file as an input, is this correct or should I use a different file. If this is the case: which file?

When running "Techgen -si <ICTfile> " I get the following error statement:

------------------------------------------------------------------------
Interconnect Capacitance Modeler Techgen64 Version s18.1.2132

Error, process analyzing failed

Does anybody have an idea how to fix this error?

This suggests that something is wrong with the consistency of the ICT file. I would suggest you contact customer support as seeing the data will make this easier to debug.

Hi Andrew,

Thank you for your reply! I am now using a test ICT file with just 3 layers and a VIA. However, since it is a test file the layers start from a specific height and have nothing in between the substrate and the first layer. Could this be the problem?

Could be - I don't know without spending time checking. That's why I suggested contacting customer support (I really have not played sufficiently with Techgen to know how it behaves with incorrect ICT files).

Andrew.

I fixed the error with Techgen and am now able to both simulate and compile my ICT file. However, I do have some problems with running Quantus. Do you have any idea how to set it up with the Techgen compiled files?
