Question

/* functions for translation between the representation actually used by
simulator and the canonical representation */
/* s=source, d=destination, w=width */
/* actual <-- canonical */
void svPutBitVec32 (svBitPackedArrRef d, const svBitVec32* s, int w);
void svPutLogicVec32 (svLogicPackedArrRef d, const svLogicVec32* s, int w);
/* canonical <-- actual */
void svGetBitVec32 (svBitVec32* d, const svBitPackedArrRef s, int w);
void svGetLogicVec32 (svLogicVec32* d, const svLogicPackedArrRef s, int w);

The above functions copy the whole array in either direction. The user is responsible for providing the correct width and for allocating an array in the canonical representation. The contents of the unused bits is undetermined.

Although the put/get functionality provided for bit and logic packed arrays is sufficient, yet basic, it requires unnecessary copying of the whole packed array when perhaps only some bits are needed. For the sake of convenience and improved performance, bit selects and limited (up to 32 bits) part selects are also supported, see Annex E.10.3.1 and Annex E.10.3.2.
