    Setting power domain locations with CPF flow Reply

    The encounter users guide says: "Manually move the power domains into the core area." This lacks a little clarity about what commands I use to do this. I have guessed it might be createFence but have no way to be sure. It seems to work but check place isn't very happy. encounter 30> checkplace **WARN: (SOCSP-364): Placer could not determine rows for 'SRC'. Will use stdCellHgt for flooded rows. **ERROR: (SOCSP-357): Could not init legalization data for powerDomain 'SRC'. **ERROR: (SOCSP-358): PowerDomain box is not valid Searching sourcelink for SOCSP yield nothing. Any suggestions?

    Hello,

    The errors here indicate setup issues.

    I suggest you run "verifyPowerDomain" after commitCPF and make sure there are no errors before continuing in the flow.

    Based on the errors it sounds like the power domains were not moved into the core area. You should not need to use createFence as this will be taking care of via CPF commit. Drag the power domain into the core area and resize as needed.

    The error "...Could not init legalization data for powerDomain" makes me think the power domain has not been dragged into the core area.....

    Here is the flow:

    loadConfig
    loadCPF
    commitCPF
    Note: You should see the power domains to the left of the design
    verifyPowerDomain
    floorPlan -site ...
    Note: This is the manual part, move/resize/reshape by clicking on the power domain and move it into the core area
    Note: You can also accomplish this via TCL using the "setObjFPlanBox Group x,y coords"
    modifyPowerDomainAttr -minGaps -rsExts
    Note: The POWER DOMAIN name above should match the name in the CPF

    At this point the basic LP infrastructure is created. You should be able to do a saveDesign (saveDesign floorplan.enc) and use this as your starting point going forward.

    Let me know if you have any follow-up questions.

    Regards,

    Elvis

    The answer turned out to be place the domain using:

    modifyPowerDomainAttr pdName [-box llx lly urx ury]
