Troubleshooting Missing Voltage Sources in Netlists

LC202506035949 1 month ago

If you're experiencing issues with voltage sources not appearing in your netlist, make sure to attach a power symbol to each voltage source. Also, rename each power symbol appropriately if you have multiple voltage sources in your design.

By attached a power symbol, it treats it as a global net identifier. Without this, the tool might not recognize the voltage source as connected to anything meaningful.

Example:
In the schematic below, a 5V voltage source is correctly connected to a power symbol named "5V". This ensures the voltage source is properly included when generating the project netlist.

Hope this helps anyone dealing with this issue!
