Hi, Im trying to merge 2 lefs together. after loading tech and stuff, im doing:
read_lef lef1.lef
read_lef lef2.lef
write_lef merged.lef
but the output lef doesnt have any pins or anything, just layer information. How can i merge the 2 lefs together properly? cant find much on solvnet.
Thanks

i tried:
read_lef lef1.lef
read_lef lef2.lef
check_workspace
write_lef merged.lef
it printed out one lef but with 2 separate macros and all their pins. however, i only want it to have one top macro. so inside the lef there would be one MACRO statement and all the pins of the 2 lefs combined under it. right now it has 2 MACRO statements and each macro has its own pins. how can i make it one topcell macro?
