+## Testing DRC and LVS for GF180 Variants
+
+To run DRC regression for GF180 variants, you could run the following commands;
+
+```bash
+make env
+make tes-DRC-<variant_name>-<table_name>
+```
+
+- Example 
+```bash
+make env
+make tes-DRC-BCDLite-poly2
+```
+
+To run LVS regression for GF180 variants, you could run the following commands;
+
+```bash
+make env
+make tes-LVS-<variant_name>-<table_name>
+```
+
+- Example 
+```bash
+make env
+make tes-LVS-BCDLite-MOS
+```
+
 ## Generating SVG for all unit tests
 
 To generate all the svg files for the unit tests run the following commands;
 ```bash
 make env
-make svg
+make gen-svg
 ```
 
 This will run the [`./scripts/generate_svg.py`](./scripts/generate_svg.py) to
