2. Kwisithuba sesithuba isithuba sefestile yoMphathi woMnyanzelo, cofa eNtsha ukwenza iSDC entsha file, kwaye igama le file. Imiqobo yoYilo iquka imiqobo yemvelaphi yewotshi enokuthi ingeniswe kule SDC ingenanto file.
3. Ukuba i-Classic Constraint igeleza kwi-Libero v11.7 okanye ngaphezulu isetyenzisiwe, cofa ekunene Yenza izithintelo> Isinyanzelo sexesha, kwi-Design Flow window, kwaye emva koko ucofe Yenza uMthintelo omtsha. Idala iSDC entsha file. Imiqobo yoyilo ibandakanya imiqobo yomthombo wewotshi, efakwe kule SDC ingenanto file.
4. Bala ixesha le-TCK kunye nesiqingatha sexesha. I-TCK isetelwe kwi-6 MHz xa i-debugging yenziwe nge-FlashPro, kwaye imiselwe kwi-frequency ephezulu ye-30 MHz xa ukulungiswa kwempazamo kuxhaswa yi-FlashPro5. Emva kokuba uligqibile eli nyathelo, ngenisa le miqobo ilandelayo kwi-SDC file:
   yenza_ikloko-igama {TCK} \
   • ixesha TCK_PERIOD \
   • uhlobo lwamaza { 0 TCK_HALF_PERIOD } \ [ get_ports { TCK } ] Kuba exampLe miqobo ilandelayo isetyenziswa kuyilo olusebenzisa i-TCK frequency ye-6 MHz.
     yenza_ikloko-igama {TCK} \
   • ixesha 166.67
   • uhlobo lwamaza {0 83.33} \ [ fumana_iizibuko { TCK } ]
5. Nxulumanisa yonke imiqobo files ne-Snthesis, iNdawo-kunye-neNdlela, kunye noQinisekiso lweXesha stages kwi Umlawuli wokunyanzeliswa > Ithebhu yexesha. Oku kugqityezelwa ngokukhetha iibhokisi zokukhangela ezinxulumeneyo zeSDC files apho kwangeniswa khona imiqobo
