Trigger loading of 'Mark Net' settings

FormerMember
FormerMember

Hello,

I wrote a script, which uses the 'leMarkNet' function to mark a net. I noticed, that it does not work as expected, if I run my function in a fresh Virtuoso session. It does not recognize any connected shapes.

However, after I manually use the GUI function ('Connectivity -> Mark'), the script works. It seems, that some settings must be loaded, before mark net works, which is only triggered when using the GUI. 

Is there any way, to load these settings automatically before I run my script, without the need to run mark net manually before?

Best regards
Paul

  • Paul,

    It works for me. Which version are you using, and exactly how are you calling leMarkNet()?

    Hello Andrew,

    I am using 'virtuoso version ICADVM20.1-64b 06/29/2021 18:30 (cpgsrv11)'. I call leMarkNet with a starting point and a starting layer. It works as expected for the rest of the Virtuoso session in all Layouts, when I first perform a manual Mark Net (only have to do it once globally and I dont have to actually mark a net, only active the function and abort it). 

    I noticed, that I get this message "Loading pinSolutions.cxt " in the CIW the first time I try to mark a net manually. I guess this loads some required settings for the PDK?

    Best regards
    Paul

    You may try loading the context yourself just before using leMarkNet, e.g.:

    unless( isContextLoaded("pinSolutions")
        loadContext(prependInstallPath("etc/context/pinSolutions.cxt"))
    )

    I rather doubt just loading the context has anything to do with this - the context is being auto-loaded because when you do mark net interactively the first time, it has to build the form for the technology; when this happens, it builds other forms too, including some related to pins - and that's triggering the loading of the other context.

    I don't see this problem (although I wasn't running the same sub-version as you but the latest ISR, ISR23). For me it marks the net without  having ever run it interactively.

    Paul, please contact customer support.
