How to implement multiple assignments in the case statement (as like LUT)?
there is a syntax error for multiple assignments.

the 'code' range from 0-3 for a simplified version (2bit)

case(code)
0:  c1=0, c0=0;
1:  c1=0, c0=1;
2:  c1=1, c0=0;
3:  c1=1, c0=1;
default: c1=0, c0=0;
endcase

you're right
