hello people,
recently I'm playing around with my DSOquad, reimplementing the firmware for fun: while getting the various parts to work, I came to the limitations of the current FPGA configuration, so I need to reconfigure it.
the problem is, I can't find any tool to synthesize/place/route this particular model:
I tried the most recent icecube2, which is free, but it seems to works only with iCE40 ...
I gave a look to what chips the other commercial tools can work with, but the tools I had access to where marketed years before the release date of the chip, hence no support.
as a sidenote, in the icecube2 config files there are commented sections for the '65, so I tried by uncommenting them, but could be that simple ? surely not !

in fact, icecube2 can now work with it, checking/compiling my verilog, but once it passes data (the netlist, I think ?) to its synthesis backend it stops, because it's a stripped down version of synplify pro and it doesn't know the chip ... so now I'm stuck.
which tools (even commercial) support this particular chip ?
