Abstract: |
Lattice Expert 7.1 is used successfully to make a new-type digital cymometer with a Complex Programmable Logic Device (CPLD) used as virtual kernel of the cymometer,and a large programmable logic device (ispLSI1032E) used as hardware circiuit. The one chip includes strobe control circuit,count circuit,multi-choice circuit,bit-choice circuit, segment-choice circuit which are designed by ABEL-HDL.The frequency is designed from 1 Hz to 70 M Hz. The whole system passes the debugging in software simulation, software and hardware parts. |
