ERROR:MapLib:87 - There are invalid FMAPs in the design

[umairsiddiqui]

i am currently debugging the cpu code, and try for first rough fpga
implementation (spartan3 starter kit). in cpu for a short cut,
i used a xilinx macro "adsu16".

i'm using Xilinx Project Navigator 6.1.03i. the design
properly synthsize, translate but fail on mapping
and shows following error and warnings.

please help with issue.

also i would be nice if any one of you write the code of adsu16 in
vhdl or verilog??? ;-)

I don't have ISE 6.1.03i, so I tried 8.1.01i. It compiled and routed with no error messages.

 

[umairsiddiqui]

well i've made few changes in cpu code which can noted in cpu.vhd, cpu_pkg.vhd, dp.vhd and con.vhd. just search

@new

i hope this might solve some problems...but synthesis tool now report that top.vhd now support (Minimum period: 21.976ns (Maximum Frequency: 45.503MHz).

so kindly provide help with spartan 3 dcm configuration...i tried with architecture wizard but generated component has too many ports...i am confuse with this issue.

please tell me how to use dcm in top.vhd and how connected the cpu and rest of logic with "clkdiv".

any way i'm attaching the files as well, the baud_timer.vhd need to be changed as it is for 50MHz and so as top.ucf.

atleast fix the top.vhd and top.ucf, incorporating dcm related changes
