Hi @hexuyangguang 

In block design flow which you are using, the IP files are not genrated. Please add the IP as a design source (see the Vivado sources in the pic attached to my previous reply.

Hi @hexuyangguang ,

         The reload txt file is generated in the project directory. In Vivado 2020.2 it is generated in path \ <prjtname>.gen\sources_1\ip\fir_compiler_0 as shown in the attached snapshot. In previous versions it should be in "\<prjtname>.srcs\sources_1\ip\fir_compiler_0".

Are you using the FIR compiler in IPI ? The reload coefficient should follow the order shown in the coefficient reload tab. The coefficients should be re-arranged as per the reload index.

hi vkanchan,

      Thanks for your kindly replay!

      I am not using the FIR compiler in IPI!

      Just try to use the fir IP.I searched the whole directory in the project, I still can't find the order file.I am using the vivado 2017.4.

      Anyway,I am checking the coefficients order I sent to the core,It seems like the problem where it is.

      Thanks again!

Hi

The folder "BD" means block design which is created using the IPI flow.

Just instantiate the IP in design sources and generate the IP products to generate the IP related files

 I have already generated the IP products to generate the IP related files.

 It seems that the related files are different between you and me . Maybe it is determined by the vivado version.

 The reload_order.txt doesn't appears!
