ngspice: keyboard matrix challenge #32
Description
Describe the keyboard matrix as a series of branches and groups. Reference diagram:
- Is it possible with only branches and groups to describe this geometry?
- Is it possible to configure pulses to test the matrix response out via voltage level changes?
If this challenge is completed in a reasonable way that's understandable. Than the ngspice/pyspice adaptor is correctly abstracted. It is quite a complex challenge is describe such a nodal network without touching net-lists.
