@UserAfter changing:

set ::env(FP_PDN_MACRO_HOOKS) "\

mprj vccd1 vssd1 "

to

set ::env(FP_PDN_MACRO_HOOKS) "\

wb_openram_wrapper vccd1 vssd1 \

openram_1kB    vccd1 vssd1 "

I got LVS mismatch error with this log showing that for one macro vccd1 and vssd1 pins were not matched (left vs right):

Hello @User I am too encountering the same issue how did you solve it?

@User I removed FP_PDN_ENABLE_GLOBAL_CONNECTIONS and place FP_PDN_ENABLE_MACROS_GRID instead.
