DPGEN_FIFO 3 ASIM/LIP6 DPGEN_FIFO FIFO Macro-Generator #include <genlib.h> void GENLIB_MACRO DPGEN_FIFO char *modelname long flags long N Generate a FIFO of ®Number; words of &N; bits named &modelname;. How it works : &datain0; and &datain1; : the two write busses. Only one is used to actually write the FIFO, it is selected by the &sel; signal. &sel; : when set to &zero; the &datain0; is used to write the register word, otherwise it will be &datain1;. &r;, &rok; : set &r; when a word is requested, &rok; tells that a word has effectively been popped (rok == not empty). &w;, &wok; : set &w; when a word is pushed, &wok; tells that the word has effectively been pushed (wok == not full). &ck; : clock signal (input, 1 bit). &reset; : reset signal (input, 1 bit). &r; : read requested (input, 1 bits). &w; : write requested (input, 1 bits). &rok; : read acknowledge (output, 1 bits). &wok; : write acknowledge (output, 1 bits). &sel; : select the write bus (input, 1 bit). &datain0; : first write bus (input, &N; bits). &datain1; : second write bus (input, &N; bits). &dataout; : read bus (output, &N; bits). &vdd; : power. &vss; : ground.
