GDS Output?
Closed this issue · 4 comments
I see that the DFFRAM Overview:
https://github.com/Cloud-V/DFFRAM#overview
Says:
Different views (HDL netlist, HDL functional models, LEF, GDS, Timing, …) are all generated for a given size configuration.
After running the compiler, I don't see any GDS.
Is that the idea?
Is there some follow-up step which should be generating one?
Or is this an indication that something went wrong?
We honestly just haven't gotten around to doing the GDS step yet. Caught up in some issues. :(
So, how do (or would) you go about producing a GDS?
Load up one of the cells in Magic and export it?
@dan-fritchman Yes, you can use magic to generate the gds. I would follow the commands here to generate the gds file from the def file https://github.com/efabless/OpenLane/blob/master/scripts/magic/mag_gds.tcl , TECH_LEF should point to the technology lef under your PDK_ROOT (libs.ref/sky130_fd_sc_hd/techlef/sky130_fd_sc_hd.tlef) and assume that MAGIC_PAD and MAGIC_ZEROIZE_ORIGIN are set to zero
GDS output has been added, closing.
