Z8 emulator user interface

Designed to work with IBM PC computers, the Z8 emulator's Windows user interface provides: pop-up windows for Status, Source, Registers, Program, Data, Stack, Variables, Locals, Breakpoints etc. Source level debugger window for C-Z8 and assemblers. Full screen edit. User-defined Watch windows. Extensive Macro support. Unlimited user-configurable setups that hold Breakpoint, Trace and Event information for easy recall from disk. Performance Analysis and Code Scope for product optimization and monitoring. VGA, SVGA, and Laptop display support.

 
COMPLEX EVENTS

Z8 emulator complex events GUI

Event is a set of conditions that control the operation of complex program breakpoints and trace start/stop logic in real time. There are three Events available on the Z8 emulator, each consisting of a combination of the following:

Up to 256K address breakpoints or ranges
8 bit Data pattern with less than, greater than,
equal, not equal, and don't care combinations
RD, WR, INT, instruction fetch, operand read as qualifiers
External input with programmable trigger polarity


In addition, Events can be counted and delayed by the use of two 16 bit Pass Counters. An 8-level hardware sequencer is available to sequentially trigger from or to any Event or Pass Counter.


BREAKPOINTS
   Z8 emulator breakpoints

Breakpoints are used to stop user program execution preserving the current program status. Z8 emulator breakpoints can be triggered from a combination of:

Address or range of addresses
Complex Events
Register value match
External input
Pass Counters
Sequencer
Trace full condition

 
TRACE BUFFER

Z8 emulator trace buffer GUI

Trace buffer is a high speed RAM used to capture in real time all activity on the microprocessor internal bus and pins. A dedicated start/stop logic allows for filtering unwanted information from the trace buffer. The Z8 emulator trace buffer retains the selected 32K samples (frames) comprised of the following:

Address Bus
Data Bus
Control signals
I/O pins
Real Time Clock Stamp
User logic inputs (8 bits)

Trace can be started or stopped by a combination of:

GO command
Any Complex Event
Any Pass Counter
Sequencer
Trace Full condition


Additionally, the Z8 emulator trace buffer is equipped with a special internal counter to allow tracing to stop after a specified number of frames. This feature allows Trace to catch as much as 32K of small fragments (snapshots) of executed program at full running speed. The Trace contents can be examined during program execution without slowing down the microcontroller.
