【Abstract】 The ESDL language and the EHDL language were defined for hardware and software in integration environment. ESDL is a superset of the ANSI C standard which is enhanced by some data type for embedded programming. EHDL is a subset of VHDL. A discrete event based simulator was used to control the simulation running of the software and hardware. Designer can use the debugger to debug the embedded software and the embedded system. With the virtual integration environment,software designers can detect hardware related bugs early in the design cycle and hardware designers can obtain a true picture of system functionality. Both hardware errors and software errors can be encountered and repaired before fabrication of the system.更多还原
