Hi

I am trying to do hierarchical placement and hence pointing to memory lef, pad lef, std cell lef and tech lef.

Could you check that your DEF contains 'unit' in ROW statements?

e.g. the correct ROW statement would be 

ROW CORE_ROW_0 CoreSite 400512 1710816 FS DO 6803 BY 1 STEP 192 0

I guess your DEF may contain 

ROW CORE_ROW_0 unit 400512 1710816 FS DO 6803 BY 1 STEP 192 0

Hi My DEF contains the below. I am dumping DEF for standard EDA tool, and looks like, there is no option to dump CoreSite. Can you please help how were you able to dump that info?

I see...

Could you check that your previous flow contains "generating SITE [unit]"? It seems the [unit] is somehow created by your previous tool.

Three possible solutions are 1) Fix the [unit] SITE creating issue in your previous tool (recommended), or 2) If the width and height of your SITE on def is equal to SITE-CoreSite definition, manually replace 'unit' into other SITE, (e.g. CoreSite) on your def, or 3) Manually create unit SITE definition on your lef. For example

    SITE unit
        CLASS CORE;
        // the XXX and YYY must be calculated based on your generated def
        SIZE XXX BY YYY; 
    END unit

Close Issue.
