Hi.,

I urgently require the verilog code for a 8 bit Shift Register in a single Slice.,

I can design normal shift registers, in 5 slices, but I want it in 1 or 2 CLBs,

Please if someone can give me the code or can tell me how to optimize it atleast it will be great

Thanks

Hmmm... the site u showed does tht., the thing is., i can just take 1 bit out of the LUT at a time., fine yes thts 1 slice i agree., but

i need to take 8 bits out of it @ a time.,

i mean take 8 bits @ a time.,

i have implemented a SRL16, which can do the job in 8 LUTS, i.e., in 4 slices,

but am wondering., if it is ever possible to do it in 1 slice., i mean not take just 1 bit., out of the LUT but 8 bits @ a time.
 

Hey,
to design 8 bit register you need to have 8 physical outputs in one CLB. Which unfortunately we dont have. No code can be written to generate such a design that does not have physical existence.
