SoC Encounter routing help needed !

Calistudent

Hello,

I am using Cadence SoC Encounter tool. How to make sure that routing done using "Trial Route", "Special Route" or "Nano Route" is uni-directional on each layer ? For example, if M2 is horizontal, M3 is vertical and so on...

Also, how to check for routing shorts, i.e. when two nets are shorting after routing ?

Any comments on above two questions would be greatly helpful.

Thanks in advance.

  • There is no way to control the amount of non-preffered routing direction used in routing. Encounter determines this automatically based on congestion. Refer to Solution Number 11161520 on Sourcelink.

    If you're trying to route an entire block with these strict restrictions, the block probably would not route anyway. If there are only a few nets that you are concerned about, you could try using routing blockages to restrict the routing area for those specific signals and then routing just that collection of nets using the -routeSelectedNetOnly option of setNanoRouteMode.
