Create a FPGA board for raspberry

If you take the pinout file that D.L. provided and edit it to:

1. Add your additional encoders, sserial ports and PWMgens
2. Remove the inmux (actually not sure here if your hardware include the muxes or not)

Either D.L or I can take that new pinout and make a bitfile that
matches your hardware.

1. Additional encoders, sserial ports and PWMgens not needed, the pinout was created for the current scheme .
2. InMux module needed, in the current scheme used multiplexing(ICs: U1-U4) input signals IN0-IN23.

Much Thanks!!!
That looks nice. Outpus are working. I tested with  7c80v2.zip . 
Inmux is present you are right.

The second PWM isn't listed in hm2_7c80-0-pwmgen. Is it ok?
If I see a value like 0.65 at hm2_7c80.0.pwmgen.00.value I should measure a PWM Signal on IO18? Am I right?
Where can i find the encoders in HAL Configuration?

hm2_7c80.0.pwmgen.00: first pwmgen, outputs 18(PWM), 19(/Enable)
hm2_7c80.0.pwmgen.01: second pwmgen, output 37(PWM)
For enable PWMgen need set hm2_7c80.0.pwmgen.00.value and hm2_7c80.0.pwmgen.00.enable=true

hm2_7c80.0.encoder.00: 15(A), 16(B ), 17(IDX)
hm2_7c80.0.encoder.01: 38(A), 39(B ), 40(IDX)
hm2_7c80.0.encoder.02: 48(A), 49(B ), 50(IDX)
hm2_7c80.0.encoder.03: 51(A), 52(B ), 53(IDX)

Hosmot2 manual, may be useful: linuxcnc.org/docs/html/man/man9/hostmot2.9.html

Boaschti, may be you want pwmgen with dual pwm outputs(up-down mode)?

The solution was to edit config string: num_encoders and num_pwmgen.

Much thanks for helping! And much thanks for that incredible project!

At this time i have to wait for some components (out of stock )
Then i can test the board, fix some bugs, and publish on gihub.
