Standalone Synopsys Fusion Compiler Flow

Check this for Cadence one: https://github.com/celuk/cadence-flow

ICV version U-2022.12-SP4-2 or newer required, so Fusion Compiler, too. If you need to set an ICV executable that is not in your path you need to change related section in 00_setup.tcl file.

Also, if you need to give a path for fc_shell or lm_shell change them in Makefile.

If all tools are in path, there are no changes required.

Before running place all lef, gds, timing libs, tech PDK files correctly in data/lef, data/gds, data/nldm, data/tech folders.

For using another PDK, you need to modify data folder, whole 00_pdk_setup.tcl, write an ndm creation script like 00_create_ndms.tcl and you may need to change some parts of the flow for technology node specific things such as tap cells in TSMC65.

For sramless designs changing the verilog code in data/rtl, changing the constraint in data/sdc, setting top module name in 00_setup.tcl, placing required files into data folder and filling variables in 00_pdk_setup.tcl should be sufficient to run the whole flow and get a GDS that is ready for fabrication. You should have a soc verilog module for IOs such as c0_soc.v that wraps your top module.

USAGE OF THIS FLOW TOOL TL;DR

Making ndms and running the flow:

make ndms # for the first time
make all

Cleaning all ndms and flow related garbage:

make clean_all

Cleaning just flow related garbage:

make clean

Running selected scripts of the flow such as step1-2-3:

make s1 s2 s3

Removing certain blocks and steps after such as 7th block and after:

make remove 7

Show the latest block:

make show # with gui
make show_cli # without gui

Show 11th block:

make show 11

Note: After showing the blocks you can immediately run Live ICV by pressing the icon in GUI without bothering to set options again.

Following command removes 5th block and the blocks after (5-6-7-...), then runs the steps 5 and 6 and shows latest(6th) block without gui:

make remove 5 s5 s6 show_cli

Following command removes all blocks and runs all again.

make clean all

Following command cleans all garbage including generated ndms, then generates ndms, runs all the flow scripts and show the latest block at the end of the operations.

make clean_all ndms all show
