connectivity check after p&R

archive

Hi;
Thank you for the help.
Since this is my first time to use encounter, I have many problems.
When I am done with P&R and did connectivity check, I have connection problems with vdd and vss.
I have already done the following.

sroute -nets {vdd vss}

but still have this problem.
Can I check if this is a real problem?
If so, how can I solve this problem?

Thank you so much

  • Hi,
    Is your design bock or chip, and which technology??.
    I was about to ask the encounter version you are using (4.1X).
    If your setup for calibre is right and it reports as a violation it needs to be considered as a real violation.
    Like as you know that sroute command has some swatches you need to select.
    If you could not do so , then need manual work ( connecting using GUI)
    I advice you to use the below command (but depends on you requirement)

    like ex. :
    # Sample power connection
    sroute -noPadPins -noStripes \
    -noCorePins \
    -blockPinRouteWithPinWidth \
    -noPadRings \
    -jogControl { preferWithChanges differentLayer } \
    -blockPin { boundaryPins } \
    -extraConfig extra_mega.cfg \
    -nets { vdd vss }
    # extra_ub.cfg and extra_rl.cfg you
    need to generate .

    Thanks & regards
