ELC -- Characterization of cell with multi driver net

Thodoros

 Hello,

I am tring to characterize a cell that has a multi driver net.
Actually what I want to characterize is a LAT with SR function.

  • When the set signal is asynchronous ELC issues the following message:

    - illegal net ( _11\:NET06 ) is found [ 2 drivers ] : [1]:nor [2]:notif1
    => no simulation
  • When the set signal is synchronous ELC issues the following message:

    - loop recognition error ( multi stage ) loop( imux:_2\:NET06 nand:_9\:NET08 not:Q )
    => no simulation

I have managed to characterize simple LAT, NLAT, LAT with sync/async reset. However I cannot

characterize the SRLAT due to the feedback of the SET.

Can you please help me to overcome tis situation?

Thanks,

Thodoros.
