DPGEN_DFFT(3) Alliance - genlib User's Manual DPGEN_DFFT(3) NAME DPGEN_DFFT - Dynamic Flip-Flop with Scan-Path Macro-Generator SYNOPSIS #include <genlib.h> void GENLIB_MACRO (DPGEN_DFFT, char *modelname, long flags, long N); DESCRIPTION Generate a N bits dynamic flip-flop with scan-path named modelname. The two latches of this flip-flop are dynamic, i.e. the data is stored in a capaci- tor. How it works : * scan when set to '1' enables the scan-path mode. Note that in scan-path mode, the wen signal is not effective. * scin : the input of the scan-path. This terminal is different from i0[0]. The scout is q[N-1] (in the following example this is q[31]). * wen when set to '1' enables the writing of the flip-flop. TERMINAL NAMES 1. scan : scan-path mode (input, 1 bit). 2. scin : scan path in (input, 1 bit). 3. wen : write enable (input, 1 bit). 4. ck : clock signal (input, 1 bit). 5. i0 : data input (N bits). 6. q : output (N bits). 7. vdd : power. 8. vss : ground.
