IP Cores reuse

Jump to solution

Hi ,

 

We have a core generated for spartan3-676 speed grade 4 . And we would like to use the same core for spartan3-676 speed grade 5 . Do we have to make any changes to the core or can we just pull in the excisting xco core in the project for  spartan3-676 speed grade 5 and directly generate the bit file ?.

 

Thanks in advance for your help.

 

With regards

Vintu

The recommended way would be to regenerate the core for the correct speed grade. Ideally if you migrate the project, xco files will be automatically regenerated for the target speed grade

Thanks for the reply .

 

When I am regenerating the XCO files (filters whose filter coefficients are added as COE file, it gives me errors so i have to relaod the COE file from the new location). This leads to the change in settings , What do i do about it?.

 

How do i compare if the XCO files generated for the previous project is having the same settings as the current project except for the speed grade?.

 

With regards

You should be able to use a relative path for the .coe.

 

You can compare the two using any text editor. An .xco is just a text file.

Any text editor would work. You could use beyond compare to compare both the xco files.
