Placing Symbols in an PADS Designer Schematic

Use the following procedure to place symbols created in PADS I/O Designer into a PADS Designer schematic, and generate reference Designators for those symbols.

1. In PADS Designer, activate the PADS Databook Window and choose the Symbol View tab. Symbols can be selected from the local symbols partition. Symbols from the Central Library can be selected from the Part View tab.

2. Click Place Symbol to add the selected symbol to the schematic.

3. Once the symbol has been placed on the schematic it can be wired to the desired nets. It is recommended that you use the “Net Stub” technique to wire symbols. This technique consists of placing only a small wire segment from the pins, and adding the appropriate Net Label text property to the wire segment.

4. In PADS Designer, select Tools > PCB Interface, and select Create Netlist for Layout, and click OK to generate a netlist.

In PADS Designer, to determine the Reference Designator the netlist generation allocates to the symbol, double-click on the symbol to bring up the Properties Window.
