    Hi All, I'm looking to work with someone to design a PCB board for a GPS Module and suggest potential components. The module will be battery powered ( Not LiPo), need to have low power consumption, be able to run some code (max memory approx 20,000 bytes). It will work with a Tri-Band LTE-FDD and Dual-Band GPRS/EDGE module solution, most likely the 7000 series. The outcome for this proje...

    I have a very simple Cadence schematic and layout I have designed of an XOR gate. For some reason the nest lists do not match in the LVS check. I cannot figure out this simple task because I am new to the process. The layout cannot change but corrections can be applied and the entire schematic can change to make the proper corrections to match the layout.
