For batch simulation, the compiler can generate an intermediate form called vvp assembly. the test bench is fine, but when im going to implement it on fpga board its giving. Then, industry standard Xilinx ISE compiler tools are invoked and the VHDL code is optimized and synthesized into a hardware circuit realization of your LabVIEW design. A powerful feature of the PLD schematic is the ability to generate VHDL code from the PLD logic in Multisim. The best thing to do in this case is to convert the netlists to EDIF files, a readable, text file version of the netlist. These days there are efforts under way to standardize synthesizable Verilog and VHDL code. We need to implement a hardware structure that writes simultaneously at the same RAM address and read from different RAM address in the same clock cycle. While the emphasis is on the practical VHDL-to-hardware flow for FPGA devices, this module also provides the essential foundation needed by ASIC designers.
