The Simulating Testing Facture of Electron Circuitry Enhanced Function ——the emulation of logic analyse of digital circuitry

At the base of the relevant knowledge about Visual Basic database,TLL integrate circuitry and digital logic circuitry have given and briefly introduction. This thesis dilates that at the base of the old DXMS software, using Visual Basic database language to design digital logic truth table\,using checking truth table to process the simulating logical analysis of address decode and buffer locking circuitry of the electron circuitry making in the part of PCJK of simulating lab. At the end, it shows the result of the running by the time\|sequence picture of logical signal. Then it realizes emulation of digital logic circuitry.
