LI Wei-mi · Microcomputer Information · 2010
Introduced briefly the CPLD/FPGA component characteristic and the application scope,and take the frequency division ratio as 2.5 and 1.5 frequency divider designs are examples,introduced under the MaxPlusII development software,designs the numeral logic circui using the VHDL hardware description language as well as the schematic diagram input way the process and the method.This design has the structure simply,the realization convenient,is advantageous for the characteristic which the system promotes.
