How to use COE files of vivado

COE file

In some IP Configuration of core , Need to use COE（Coefficient） File to pass parameters , just as 《FPGA Digital signal processing series 》 I have used it many times MATLAB Automatic generation FIR Filter coefficient file required by the filter .

COE A document is a kind of ASCII text file , The file header defines the data base （Radix）, When you can 2、10 or 16. The data is given in the form of vectors , Each vector ends with a semicolon .Vivado Can parse COE File format , And generating IP When the kernel is exported, the related MIF Format file , For behavior level simulation .

It is best to COE The file is placed in the IP Under the same directory （ I.e XCI The files are in the same directory ）, It's working Core
Cotainer pack IP Nuclear time will also COE Package files to XCIX In file . When replacing COE When you file , The old must be deleted COE file , Otherwise, it will be transferred to the comprehensive process of the project ; We need to pay attention to , If you just delete the file on the disk , Instead of removing in the project , Will cause a report error.

COE File syntax
COE The general syntax format of the file is as follows ：

Keyword =Value ;  notes
