exception handling in skill/ocean

swdesigner
I searched the community and support.cadence, but couldn't find any reference material or source code examples showing how to handle exceptions in skill/ocean.

For example, my ocean script loops voltage using foreach to do several runs. After each run, I do some postprocessing. If some of the post-processing fails because a condition being looked for in the simulation is not found, I want the rest of the runs to complete. Instead what happens is the ocean script exits with an error.

For example, if I am looking for  a rising edge on a certain signal and it doesn’t exist..

Any help will be great.

  • If you want iPad, use ADE XL - which captures much of this in a UI. Programming languages are by nature flexble - and with flexibility comes (unfortunately) the need to cope with unexpected situations - it's very hard for a general programming language to do the right thing if it has no idea what the right thing should be given that your code could do anything...

    And yes I did mean eloquently (well written (yes, strictly it's well spoken, but I thought I'd be free to adapt my own language!)), but "elegantly" fits too.

    It really shouldn't be intimidating. Usually the conditions don't have to be complicated. I normally advise people to use things like:

    unless(member('tran results())
      ...
    )

    to check if the transient results are present - little idioms like this are easy enough to remember, even for non-programmers (and most engineers should have at least some programming knowledge these days).

    Glad they take the OCEAN class (I wrote it!). Surprised it's not used that much though - I tend to find many users who do because of the flexibility it gives them.
