If I create an sc_lv 42assignment with range methods on every side like 43 44lv1.range(15,8) = lv2.range(7,0); 45 46and the lv2 vector contains "z", I get the warning message 47 48WARNING: (E2004) sc_bv cannot contain values X and Z : 49 - ../../../../../src/sysc/datatypes/bit/sc_bv.h: 340 50 51and the assignment is not done. Further investigation revealed that the 52vector seems to get mistakenly converted to a sc_bv in between. Removing the 53range method on one side or adding a cast 54 55lv1.range(15,8) = (sc_lv<8>)lv2.range(7,0); 56 57solves that problem. 58 59Regards, S. Heithecker 60*/ 61 62#include "systemc.h" 63 64int 65sc_main( int, char*[] ) 66{ 67 sc_lv<16> a( "01ZX0000111101ZX" ); 68 sc_lv<16> b; 69 70 b.range( 15, 8 ) = a.range( 7, 0 ); 71 cout << a << endl; 72 cout << b << endl; 73 74 return 0; 75} 76
