## The ZipCPU's Simulator

This directory contains the basic ZipCPU simulator.

Ok, even this isn't the *best* simulator of the ZipCPU.  While this simulator

*is* fully functional, it only simulates the

[ZipCPU](../../rtl/core/zipcpu.v), encased in either the

[ZipSystem](../../rtl/zipsystem.v)

or the [ZipBones](../../rtl/zipbones.v),

plus [memory](memsim.cpp).  This simulator doesn't handle any interactions

with the

[flash](http://opencores.org/project,qspiflash), the

[serial port](https://github.com/ZipCPU/wbuart32), the

[SD-card](https://github.com/ZipCPU/sdspi), etc.  All of these interactions

(and more) are available from the

[simulator](https://github.com/ZipCPU/zbasic/tree/master/sim/verilated)

within the

[ZBasic repository](https://github.com/ZipCPU/zbasic).

However, this simulator *is* very basic to the CPU's functionality.  If you

just want to know if the CPU works by itself, if it can properly execute the

instructions given to it--even to the point of testing

interrupts etc, then this simulation will work.  It's just not fully

functional for testing all of the other peripheral components necessary

to make a CPU useful.
