siliconblue/lattice iCE65L04 anyone ?

[dmy]

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 ?

AFAIK Lattice killed the iCE65 almost immediately after acquiring Silicon Blue, so you're probably out of luck, at least as far as free tools are concerned.

these are sad news ... I won't surrender though.
I'll try to politely ask lattice or seeedstudio, surely it won't hurt.

thanks for the reply
