how i can know the area of my code in bit ?

[sharkya2a]

hi all,

after doing the Synthesize for my VHDL code

Xillinx ISE show the area values as device utilization, it shows:
Number of Slice Registers
Number of Slice LUTs
Number of fully used LUT-FF pairs

which one of them reflect the space or the area needed by the VHDL code to be stored on the device ?

how i can know the area of my code in bit ? is there anyway to convert Number of Slice to its equivalent value in bit or Byte ?
because i need to know how much area my VHDL code need, to decide if it is fit on sensor or not.

best regards

number of bits is irrelavent. the number of LUTs is the important number

i mean the code size of the implementation, there are some researchers I want to compare my code with their codes.
for example one of them says that the code size of his implementation only takes 18.8 KB ROM and 1.36KB RAM.

so, how i can know how much my implementation takes size in ROM and RAM.

best regards

again, thuis has no meaning unless you actually implement roms or rams

Dear TrickyDicky,

thanx for your interest

you told me that the number of LUTs is the important number, which describes the area.
is there a way to know if this number of LUTs fit for a specific devise or not. for example for sensor.

best regards

the build report will tell you the usage %
if it wont fit, you will get an error.
