The "starter" version, which may be freely downloaded from Lattice
accepts only the "schematic" entry and the ABEL.
I think that the ABEL backend could be uselful also for other EPLD
devices...

Could you give me some pointers, how get the information just in that
form (in fact the ABEL compiler may be fed with such information
after a small preprocessing <ie. building of nodes declarations, and
building of equations on the basis of netlist>).
Maybe the possibility to output the generated netlist in the ASCII
format would let us - the users, to create the "batch converters"
for different EPLD tools provided by IC manufacturers?
I think that for many of us it could be easier to write the perl, or
python based program working as a postprocessor of IV generated netlist,
than to write the backend in C++ and to integrate it with rest of IV.
Such solution should be also more robust to changes occuring during the
development of IV.
