PR VHDL Example

Hi,

 

I'm new in partial reconfiguration, I followed the ug702 guide, but unfortunately the example is written in verilog.

I'm searching for source codes written in VHDL. I found old one which uses a bus macro, I didn't understand what is a bus macro and if it is still used with new designs or they used it because the tools wasn't suuport the PR well.

 

Thanks,

Re: PR VHDL Example

I don't have a VHDL design example, although the tutorial design could probably be converted with fairly minimal effort.

 

Don't use any design that has bus macros.  These were for a very old form of Partial Reconfiguration, and we replaced in the ISE tools with Proxy LUTs.  If are you new to PR, I would also highly suggest you use Vivado.  It is the same license currently, and this just went to production status in 2013.3.  There are two documents on the Vivado Design flow:

 

UG909 - Partial Recofiguration User Guide

UG947 - Partial Reconfiguration Tutorial

 

This flow does require the Vivado 2013.3 tools.

 

I hope this helps.

Re: PR VHDL Example

Thanks alot for your reply, bus macro was a very boring thing.  I'll try the other program flow I hope it will be easy.

Re: PR VHDL Example

Hi,

There is a reference to a sample design (led_shift_count) in the UG947, but I can not find the led_shift_count_2013.3.zip, neither in the VIVADO insallation folder, nor on the xilinx website. Can you give me a hint where to search?

Bests, Christian

Re: PR VHDL Example

I just found it by simply using the main search on the xilinx site (use ug947 as search pattern).
