DPGEN_SHIFT 3 ASIM/LIP6 DPGEN_SHIFT Shifter Macro-Generator #include <genlib.h> void GENLIB_MACRO DPGEN_SHIFT char *modelname long flags long N Generate a &N; bits shifter with name &modelname;. How it works : if the op[0] signal is set to &one; performs a right shift, performs a left shift otherwise. if the op[1] signal is set to &one; performs an arithmetic shift (only meaningful in case of a right shift). &shamt; : specifies the shift amount. The width of this signal (&Y;) is computed from the operator's width : Y = ceil(log2(N)) - 1. &op; : select the kind of shift (input, 2 bit). &shamt; : the shift amount (input, &Y; bits). &i; : value to shift (input, &N; bits). &o; : output (&N; bits). vdd : power. vss : ground.
