Where are Custom Calculator Functions stored when loaded by fx button

Volker T

Dear all,

does anyone know where the code of a Custom Calculator Function gets stored when I load a SKILL file as a custom calculator function using the "fx" button in Calculator?

The problem is, that one can mess up Cadence ADE and the Calculator so badly, that it crahes (or rather freezes up) permanently, i.e. even after re-starting Virtuoso and then invoking Calculator again.

It must be somehere in the user's project home, because when restoring the whole home directoty to the state it was before, Calculator can be started again without freezing up.

However, a manual inspection does not point me to what file may cause the trouble.

Edit 1:

There is a comment by Andrew Beckett in another post, that says: "When you use the "fx" button it actually adds it into your home directory's .cadence dir, not the working directory, so it should be visible across multiple workspaces for then same user. "

Edit 2:

Andrew is right. It's in the HOME not project home.

HOME/.cadence/dfII/viva

In there, there is a file cusomFunctions.ini, and in this file, I can see the path to the SKILL file.

However, I don't understand then why restoring the project home directory solved the problem of a freezing calculator... Maybe the code goes in some sort of Cache that needs to get cleaned.

Apparently, the freezing up can be achieved by using string escape characters in the tooltip of a parameter in the ocnmRegGUIBuilder section, like

tooltip "Edge type 1. Either \"rising\" or \"falling\""

  • The issue with embedded quotation marks is clearly a bug - I filed a change request (CCR) 2939660 to get that fixed. There's no caching - it's the reference to the file with the builder tooltip that contains the embedded quotation marks that's the problem.

    By the way, you can put HTML tags like this:

    tooltip "Edge type 1. Either <I>rising\</I> or <b>falling</b>"

    instead if you want text to stand out (of course using italics and bold inconsistently is not what you'd do here, but this is to illustrate the point).
