I'm designing a PCB in Altium that contains three of the same motor driver IC's (L6470H) which all communicate via SPI bus. As you can see below, I have repeated blocks to avoid redoing the same schematic.
The problem I'm having is related to merging the ports of every block so that they connect to the a single MOSI and MISO pin on my microcontroller. What I am currently doing is taking the SPI bus from every block and creating a bus which will be terminated elsewhere in my hierarchical design.
In my higher level schematic below, I attempted combined buses by simply terminating a MOSI bus into a single MOSI wire thats connected to my STM microcontroller. Although the schematics do compile, my PCB layout is missing a rats nest between all the SPI pins for the motor drivers and microcontoller. As a result, I dont think my method is correct and could really use some advice!
How do you short pins between repeated blocks?
Thank you.
