Looking for help with changing stdVia's up and down in a layer set/list...

aknopp
Hi all, I'm looking for some help from someone who has some skill programming experience that could help me create a simple routine that will allow a user to select a stdVia in virtuoso and be able to cycle through (both up and down) a list of vias. Thank you, Aaron

    Hi  Aaron,

                   I have a solution for you. First set the a function which assigns a number for all standard vias in your pdk uniquely. Say set met1-met2 via as no 1 , met2-met3 via as no 2 and so on. Also set a function for finding the via name form given integer. Say if 1 is given then it will find met1-met2 via etc. After that just write a procedure that finds the number for the given via. Then according to the bindkey pressed it will increase or decrease the integer and find its euivalent via. After that all that is left is to change the via name of the selected one.

    This is just a hint. Does it solve your problem?
