    Hi Hylton,

    have a exactly look at your pin assigns and pin names!

    That was my error.

    Now it works!

    Regards,

    Josef

    I have the same problem using the HPC II core for DDR2. Version is Quartus 10.0.SP1 with patch 1.122 installed.

    The exact error: 

    Internal Error: Sub-system: ASMCC, File: /quartus/comp/asmcc/asmcc_bitfield.cpp, Line: 882
Assembler bitfield error: Found conflicting assignments for CFF address; address = 38441

    I have the problem too with QII 10.0 Sp1, DDR3 Patch 1.122

    The patch http://www.altera.com/support/kdb/solutions/rd09232010_251.html

    don't solve this problem. It seems to be a new one.

    I have these Error:

    Internal Error: Sub-system: ASMCC, File: /quartus/comp/asmcc/asmcc_bitfield.cpp, Line: 882 Assembler bitfield error: Found conflicting assignments for CFF address; address = 27879

    Tried the change but it didn't work. I created a SR for this.

    Any other ideas?

    you will have to hand edit the altmemddr_0_phy_alt_mem_phy.v: 

    $ diff altmemddr_0_phy_alt_mem_phy-original.v altmemddr_0_phy_alt_mem_phy-fixed.v 
2912c2912,2913
<             .sreset          (seq_clk_disable || ctrl_clk_disable),
---
>          .sreset     (1'b0),
>      //        .sreset          (seq_clk_disable || ctrl_clk_disable),

    i've seen something like this, are you using a DDR memory core?
