look up table in VHDL (not targeting to FPGA )

[Safiya]

HI,
Can we design a look-up table without targeting to FPGA , means using standard FETs in cadence. ?
I am new to look up table and vhdl.
thanks

You should be able to do this. You would want to ensure that it fits into the appropriate construct for the device/technology. For example, if your tools have the ability to create an optimized RAM structure, you should do whatever is needed for that. Your tool vendor may also have components for this purpose as well.

Can you please elaborate, what exactly you want to design with those look up tables ?

BTW, Look up tables are set of all possible values with set of inputs, hope this helps.

Actually i have to do something like this (example) ,
stored data as constants. just indexing with 4bits should give us corresponding data.

if 0001 then 00101010
if 0011 then 00101111
if 0110 then 00111110
if 1000 then 11101010
if 1100 then 01101010
indexing With high speed may be 1MHz,
