Hi,
I am trying to use a PMI ROM memory block in Lattice Diamond/VHDL:
decoder_rom0 : pmi_rom generic map ( pmi_addr_width => 3, pmi_data_width => decoder_rom_data'length, pmi_regmode => "noreg", pmi_gsr => "disable", pmi_resetmode => "sync", pmi_optimization => "area", pmi_init_file => "i2c_decoder_rom.mem", pmi_init_file_format => "binary"
) port map ( Address => std_logic_vector(decoder_rom_address), OutClock => clk, OutClockEn => trigger, Reset => reset, Q => decoder_rom_data );
At a later stage the compiler fails with:
Loading NGO design 'lngotmp/pmi_romebi2c_decoder_romasdn43512db0f16b.ngo'... ERROR - Pin mismatch between block 'i2c0/pmi_romECbinaryi2c_decoder_rom.memareasyncdisablenoreg43512', TYPE='pmi_romEbi2c_decoder_romasdn43512db0f16b', and file 'lngotmp/pmi_romebi2c_decoder_romasdn43512db0f16b.ngo' at pin 'Address[2:0](2)'. Done: error code 2
Synplify synthesizes the bitstream without a warning, so the issue must be related to the LSE. What can I do with it?
Best regards, Piotr
