ViVa Calculator Functions Source Code

Hi,
I was looking to find the source code (SKILL) of functions in calculator and found the following which is locked. Is there a simple way to see those? For instance, rms, dft,... etc.

A description of the algorithms and other parameters used in each Calculator functions is available in the "Virtuoso Visualization and Analysis XL
User Guide" at the On-line support site:

Virtuoso Visualization and Analysis XL User Guide -- Calculator Functions - Calculator Functions

I believe the SKILL code for each function is proprietary. If you have a question on a specific function that is not answered to your satisfaction in the User Guide mentioned above, I might suggest you either contact Customer support or post a question on the Custom IC forum.

That seems to be a totally different question that your initial question of "I was looking to find the source code (SKILL) of functions in calculator". In any case, There are both a document and a video detailing how to add a custom function to the Calculator at the On-line support portal at URL:

https://support.cadence.com/apex/ArticleAttachmentPortal?id=a1Od0000005xHHUEA2&pageName=ArticleContent

respectively. There is also a repository of custom SKILL functions that are provided buy Cadence at URL:

support.cadence.com/.../ArticleAttachmentPortal

Many are those provided by Andrew Beckett over the years in response to many questions in this Forum. You may also contribute your own Calculator SKILL code functions for others to use at URL:

support.cadence.com/.../submitsolution

If you still have not procured access to the On-line support portal(one again, I might suggest you seriously consider this), an old Forum post provides an example of a custom SKILL function for the Calculator and the method to invoke it in the Calculator.

I would have provided this information initially if I realized this was your question illaoi,
