altasmi_parallel netlist for Cyclone III

Hi,

I'm having an issue with a Cyclone III design and Precision Synthesis.

Using Quartus 11.0 I have generated the _syn.v netlist of the ASMI core and explicitly set the target FPGA as Cyclone III. However the generated netlist uses some cycloneii_* primitives. This is no issue when doing Altera-only synthesis, but I'm using Mentor Precision...

Mentor Precision fails due to "unknown cycloneii library". This is in my opinion not a Precision issue, Quartus SHOULDN'T generate a Cyclone III netlist with reference to Cyclone II primitives.

This is what I get from Precision:

# Error: : Unable to resolve reference to an Instance: cycloneii_asmiblock2 of Cell work.cycloneii_asmiblock.
#  Error: : Unable to resolve reference to an Instance: ram_block15a_0 of Cell work.cycloneii_ram_block.
#  Error: : Unable to resolve reference to an Instance: counter_comb_bita_0 of Cell work.cycloneii_lcell_comb.

The same design will synthesize smoothly if I set the FPGA type in Precision to Cyclone II.

Has anyone dealt with this issue?
