Special routes with opens

Stewan

Hello everybody,

I am working on floorplanning of a specific design with macro blocks (RAMs) and I have some issues :
1) My RAMs aren't connected to VDD/VSS

2) Number of Core ports routed: 0  open: 27478
    Number of Followpin connections: 13739

3) When I make a verifyConnectivity, I have a message below:
Error Limit = 1000; Warning Limit = 50
Check specified nets
*** Checking Net VDD
Net VDD: has special routes with opens.
*** Checking Net VSS
Begin Summary
    84 Problem(s) (ENCVFC-200): Special Wires: Pieces of the net are not connected together.
    84 total info(s) created.
End Summary

NB : I am using EDI v14.10.000

globalNetConnect VSS -type pgpin -pin VSS -instBasename * -override -verbose
globalNetConnect VDD -type pgpin -pin VDD -instBasename * -override -verbose
..

verifyConnectivity -nets {VDD VSS} -type special -noAntenna -noWeakConnect -noUnConnPin -noUnroutedNet -error 1000 -warning 50 -geomConnect

  • If the RAMs have boundary pins which should connect to rings and stripes then you need to run 'sroute' with '-connect {blockPin}'. If the RAMs have ring pins then they get connected with addStripe.

    Hope this helps,

    Brian
