Process antenna violation?

Hoang Nguyen

Hi, 

I already set options to fix process antenna violations:

- setNanoRouteMode drouteFixAntenna true
- setNanoRouteMode routeInsertAntennaDiode true
- setNanoRouteMode routeAntennaCellName FILLANT1 (process C35B4)

However, the Process Antenna violation tool still reported more than 60 violations. I also tried to set routeAntennaCellName to automatic mode but result was the same. In the routed design, I can find only one cell of kind FILLANT1. There is plenty of space around violations points to place diodes but Nanaroute did not do that.

I exported and run verification in Virtuoso but number of violations was still big (~40).

Do you know how to reduce number of process antenna violations in Nanoroute ?

Thank you very much!

Hoang

  •  Hi Hoang,

    Did u check the below setting in nanaroutemode.

    setNanoRouteMode -drouteEndIteration default

    According to this can also influence your antenna fix by nanaroute.

    This setting should be in "default" mode,

    if any numbers for iteration (ex:"20") then nanoroute doesnt fix the antenna violation.
