The pBlazIDE ISS does not support full simulation of the PicoBlaze microcontroller embedded with all the other FPGA logic. Fortunately, the PicoBlaze core source files support both VHDL and Verilog simulation using the ModelSim simulator. ModelSim allows the entire design to be simulated, including accurate timing information and textual disassembly features.
If using the Xilinx System Generator software, there is full development and
