Honored ContributorHas anyone used a HEX (Intel format) file to infer a ROM? I'd like to build a look-up table for waveform generation using a 32768 x 16 ROM and would prefer not to type in all of the values manually.
Is there a better way to do this? Thanks, Brian
Honored Contributoris this SIN is an inbuilt function in that library?
will it create a problem while synthesizing it???Honored ContributorSIN is a function in the math_real VHDL library. It can be synthesized in that case because it is calculated at compile time by the VHDL compiler. The synthesizer will just create a ROM with all the sine values precalculated.
It wouldn't be synthesizable if it were calculating the sine of a signal. In that case you could use a megafunction instead.
