I have the following piece of code which the Vivado simulator doesn't seem to support (results in ERROR: [XSIM 43-3209] - Unsupported Construct):
assign b = {<<{a}};
Wondering if I can just change this code to the following:
assign b = a<<1;
Could someone please confirm that the 2 lines above are identical? Note that both a and b are 8 bit wide. Thanks!
No they are not the same. {<<{a}}
is a bit reversal. Assuming a
was declared with the range [7:0]
, you would need to write
assign b = {a[0],a[1],a[2],a[3],a[4],a[5],a[6],a[7]};
