Hello every one
Could you please explain for me a little about hardware replication in FPGA? I prepared an ASM (Algorithmic State Machine) and want to reduce it. I found that one way is "hardware replication", but I need more info about it. If you know about it please help me by some practical examples (circuit and VHDL code).
Regards
Mostafa.
 

Re: Hardware Replication

A quick search on Google gives you a result on how to use generics and generate. Is that what you are looking for?
 

Re: Hardware Replication

Hi
I know how to use them to replicate the components, but I want to know that how does it lead to reduce an ASM? In fact by this Technique I want to reduce an ASM and determine operations which are allowed to be run concurrently.( in hardware version)

Re: Hardware Replication

"hardware replication" technics is used by synthesis tools to get higher operating frequency, the tool replicates a piece of logic
with high fan-out to reduce number of driven gates and to make source-sink connections shorter.
If this is your case - you should switch off this option in your tool if your goal is gates count reduction;

Re: Hardware Replication

Dear j_andr
What I mean is replicating hardware in design level. Note that synthesis level follows after design level.
