74348**BUG** Concise problem statement: Steps to reproduce bug: 1. Open the schematic 'Afstandbediening' that I shared with support@easyeda.com 2. Visually inspect that there is a bus with entries TMR_A, TMR_B, TMR_C and TMR_G connected to Arduino Nano's A4, A3, A2 and A1. 3. Visually inspect that this bus goes to TMR_GEN/74138 pins 1, 2, 3 and 6. 4. In the generated, autorouted PCB, find the 74138 IC (Labelled TMR_GEN. It's next to the Arduino's Vin PIN). Pin 1 (square pad) is labelled as TMR_A. Follow the generated trace to the Arduino chip. Take a note of the PIN it's connected to. 5. In the schematic, again, visually inspect that there is a bus with entries KA0, KA1 and KA2 connected to Arduino Nano's A7, A6 and A5 pins. 6. Visually inspect that this bus goes to 8_TO_3/74348 pins 6, 7 and 9. 7. In the generated, autorouted PCB, find the 74348 IC (Labelled 8_TO_3. It's in the bottom next to R1 to R9). Pin 6 is labelled as KA2. Follow the generated trace to the Arduino chip. Take a note of the PIN it's connected to. Results: Pin 1 of the TMR_GEN chip is connected to Arduino's D9 pin. Pin 6 of the 8_TO_3 chip is connected to Arduino's D11 pin. Expected results: Pin 1 of the TMR_GEN chip is connected to Arduino's A4 pin. Pin 6 of the 8_TO_3 chip is connected to Arduino's A5 pin. Solution: In the package, pin A4 and A5 were given pin number 12 and 14, and not 23 and 24! That is a hard problem to find!
