hi,
how can we interduce two or more architecture for one project and
select one for synthesize,,
the other architecture that they weren't used has any effect in synthesizing?
what's your idea?
Ok here you are, if you are using two architecture in sperate files XST will take the first file you enter in sequence the otherfile will not be included in the tree you will find it above the project tree. However if the architectures are in teh same file XSt will just take the last architecture unless it is commented with--synopsys translate_off.
Hi,
Configuration statement is meant for what you want. Please refer any text book on VHDL and start reading about configurations. You can have any no. of architectures for an entity and associate any one for synthesis and simulation with the help of configuration statements. Configurations provide many more things. Read text to get the best result.
I have done the synthesis part in Xilinx using XST, but for the implementation it do requires NGC file or NBD file, but i did not get the file, from where i have to look for the file,
Are you getting other errors?
Other kinds of errors can prevent the generation of these files.
Scroll backwards in the output window to see other errors.
