Open msinger opened 3 years ago
Just wanted to throw this out there, because I think it is interesting: After eliminating VAVE
in #22 and "re-connecting" VYPO
in #20, the net labelled P10_B
is the only one that has those pesky cells labelled "BUFFER?", which may or may not be inverting. Maybe this "discovery" helps somehow in finding the actual driver of this net.
Here are all the "BUFFER?" cells:
@msinger , I have come to the same conclusion as you regarding these cells. If incorrectly named net P10_B becomes GND, everything works properly in my PPU simulation.
@rgalland thank you very much, that's great to know. I haven't simulated the PPU yet, so I wasn't sure about this ground connection, until now. ^^
On page 5, the output of
KALE
is wrongly labelledP13_C
, it should beP13_D
. On the same page, the outputs ofKOLE
andKYTO
are wrongly labelledP10_B
andP11_B
. They should be labelledP10_A
andP11_A
respectively.P10_B
,P11_B
,P12_B
andP13_B
are all connected to each other directly at the IO ports. This connection is nowhere to be found in the schematics.On page 2, the inputs of
KERY
all should have the_C
suffix.The label
P10_B
is widely used throughout the schematic.KOLE
is not the driver of this net.KOLE
drivesP10_A
as already mentioned above. I retraced the wholeP10_B
net but I wasn't able to find the actual driving cell.
