KEY FEATURES

 
USER INTERFACE

Designed to work with IBM PC computers, the 8085 emulator Windows user interface provides: multiple pop-up windows for Source, Registers, Memory, Stack, Variables, Locals, Commands and others. Source level debugger window for ASM-85 and C-85 with automatic link to the Trace window, user defined variable SFR and Watch window.

 
COMPLEX EVENTS

Complex event is a set of conditions that qualify emulation breakpoints, event sequencer, or trace filtering in real-time. There are three 8085 complex events available that may be used for the following: 64K address breakpoints or ranges 8 bit data pattern with less than, greater than, equal, not equal, and don't care combinations. Qualify on RD, WR, INT, instruction fetch, operand read external input with programmable trigger polarity, all events may be counted or delayed by the use of two 16 bit pass counters. An eight level hardware sequencer is available to sequentially trigger from any event or pass counter.

 
BREAKPOINTS

Breakpoints are used to stop user program execution while preserving the current program status. 8085 breakpoints can be triggered from a combination of:

 
TRACE BUFFER

Trace buffer is a high speed RAM used to capture in real time all activity on the microprocessor bus and pins. A dedicated start/stop logic allows for filtering unwanted information from the trace buffer while executing. The 8085 emulator trace will store up to 32K samples (80-bit frames) comprised of the following:

The 8085 trace may be filtered before the information is stored with the use of complex events, and after the acquisition by choosing the filter menu. The trace is equipped with an internal counter to allow tracing to stop after a specified number of frames have been captured. This feature allows the trace to capture as much as 32K of small program fragments no matter how distant in time. The trace contents can be viewed during program execution without stopping or slowing down the microprocessor.
