When getting accustomed to the ZPU, a BRAM ZPU with a UART -is a good place to start. -<p> -You'll find a working simulation script in hdl/example/simzpu_small.do and hdl/example_medium/simzpu_medium.do, which -show simulation of the small(zpu_core_small.vhd) and medium sized ZPU(zpu_core.vhd). hdl/example/simzpu_interrupt.do -shows use of interrupts. -<p> -When implementing the ZPU, copy the following files and modify them to your needs: -<ol> - <li>hdl/example/zpu_config.vhd - set up RAM size here - <li>hdl/example/helloworld.vhd - dual port BRAM implementation. -</ol> -Obviously you must also connect the ZPU to the rest of your IO subsystem.

The instruction set simulator has the capability of taking -this file as input in order to verify that the HDL implementation matches the instruction set simulator. -When a mismatch is found, the GDB debugger will break.
