THE VHDL file and PDF for that is attached here

View attachment fft_fir_filter_latest.tar.gz


Hi;
i have downloaded the fft based filter from opencore and wanna simulate it with ISE for spartan6 l x100 , but it have some unspacefic errors,

can any one tel how to solve it?

dear friend i have attached the program in first line of my post please simulate and tel me what is the cause of the errors.

there is no specific error !!!!

errors:

ERROR:HDLCompiler:40 - "E:\Users\FFT_Filter\alfft_core_slip.vhd" Line 328: control is not a entity
ERROR:HDLCompiler:66 - "E:\Users\FFT_Filter\alfft_core_slip.vhd" Line 328: control is not an entity
ERROR:HDLCompiler:854 - "E:\Users\FFT_Filter\alfft_core_slip.vhd" Line 95: Unit <alfft_cores> ignored due to previous errors.

If there is no error then it must be working. You've done nothing to make anyone want to spend any effort to setup and run a simulation. You seem more interested in testing our ability to run a simulation and tell you what is wrong than lift a finger to tell us what you think is wrong and why.

And consider reading this...http://www.catb.org/~esr/faqs/smart-questions.html
 

Dear friend I apologies if i asked badly;

in fact i need to scan 0-10 Mhz frequency band and i wanna use this core to do it.

but i have receive these errors:

ERROR:HDLCompiler:40 - "E:\Users\FFT_Filter\alfft_core_slip.vhd" Line 328: control is not a entity
ERROR:HDLCompiler:66 - "E:\Users\FFT_Filter\alfft_core_slip.vhd" Line 328: control is not an entity
ERROR:HDLCompiler:854 - "E:\Users\FFT_Filter\alfft_core_slip.vhd" Line 95: Unit <alfft_cores> ignored due to previous errors.

when i'm runing the simulation.

i suggest that its my wrong not the program. but i cant find the problem because errors are not clear and have no comment with themselves to help me;

i will be thankful to have your points on it please.

thanks alot
 

Did you compile control_slip.vhd? That is the file where the CONTROL entity is described.

I'm not sure this is the correct syntax for an entity instantiation: U_CNTRL:entity CONTROL(CONTROL_SLIP), but as I'm not a VHDL guru I can't say for sure, but examples I've found online show something more like U_CNTRL : entity work.CONTROL

Besides this you've also included a component declaration for CONTROL along with the entity declaration? Either use one style or the other, I'm not sure what happens if you have both for the same component.
 

from a quick look, it appears the alfft_core_slip has a component called control that doesnt match the control entity definition in the control_slip.vhd.

I would generally stear clear of stuff on opencores.org. It's far too easy to get code that is badly written and unmaintained.
