When using hierarchical schematic blocks, is there a way to have per-block parameters/arguments?
For example, you instantiate an LDO block three times but set the values of the voltage divider resistors to different values in each block to generate different output voltages.
Right now, no. In the future this could be addressed by variants as these operate on the flattened netlist. Anyhow, doing it that way would be somewhat surprising.
Your suggestion to put the resistor outside of the block seems to be the more straightforward solution to me,
I agree. Bringing the voltage divider resistors out of the block is more explicit. Thanks for all your hard work!
