`fire_like_ravens` support. #21

Closed keegandent closed 1 week ago

keegandent commented 3 weeks ago

Problem

One of the parameters called out in #20. The FPGA RISP Processor currently does not support fire_like_ravens set to true. This narrows the ability to test RISP networks which could otherwise perhaps easily be migrated to RAVENS.

Proposed Solution

From my observation, this should be achievable by making fire from a wire (combinational logic) into a register (flip-flop logic) when the FIRE_LIKE_RAVENS parameter is true.

Hurdles

Important to note that neuron potential resetting should not depend on the value of the fire flip-flop, but rather the input. will_fire or fire_cond might be good names for such a wire.

Expected API Impacts

This should create a compatibility improvement for the fpga.Processor.load_network() function.

Noting this shouldn't be worked before a fix for #15
