Honored ContributorMultiplication by constant
Hi all. Just found out that Quartus does not instantiate hard block multiplier if multiplication is done by a constant. Even if i define multstyle = "dsp", why?

Honored ContributorThanx for fast reply, however it was a simple typo, so now synthesis multstyle works fine :). So not to create one more thread, ill ask here, for example i need to partially connect some modules output (let it be 8 most significant bits of 16). The straightforward solution is:
mult mult_inst(
.a(a_8bit),
.b(b_8bit),
.res(c_16bit)
);
assign c_8bit = c_16bit
