Problem with auto via using custom via variant

blankman

Hi,

 

I’m, looking to create a custom via variant, and then use this in the auto via tool. However when I go to do this the number of rows/columns generated doesn’t fill the selected metal area, only uses the number defined in the custom via variant. Is there a means of setting the auto via tool to fill the full metal area using the custom via variant?

 

Thanks,

Brian.

    Thanks,

     

    What I’m looking to do is to via from metal 1-4, using a via with non-default spacing of 0.49um. I create the via variant with this spacing. I then set the auto via tool to use this via variant, however it then does not fill the entire metal polygon with via, only the amount set in the via variant, ie 2 vias. What I want is the auto tool to fill the full polygon with 0.49um spaced via. Hopefully this is more clear.

     

    Regards,

    Brian.
