I'm working with a schematic in Eagle and I use IC's with different types of power pins. I connect VDD to VCC to +5V and I connect GND to VSS to zero volts.
When I look at the ERC, I receive warnings as follows:
WARNING: Sheet 1/1: POWER Pin IC1 VCC connected to VDD WARNING: Sheet 1/1: POWER Pin IC1 GND connected to VSS WARNING: Sheet 1/1: POWER Pin IC5 V+ connected to VDD WARNING: Sheet 1/1: POWER Pin IC5 GND connected to VSS
When I switch over to PCB manufacturing mode, it seems that not all the pins are connected.
My schematic has a microcontroller, CMOS IC's and a 555 timer.
Do I need to add resistors between each of the different power supply designations? I'm trying to be legal so that no electrical software complains.
