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?
