  • Wide range of µP pods to emulate most MCS-96 family members
  • Remote debugging over TCP/IP network
  • Win95 and NT user interface
  • Serial interface to the host PC

User Interface

The Win95 and NT user interface is designed to work with the Pentium computers and provides multiple windows for Source, Registers, Memory, Stack, Variables, Locals, Commands, Coverage Analysis, and others. The source level debugger window is capable of working with all major C-96 and PL/M-96 compilers and links symbols automatically to the Trace window. The user defined SFR and variable Watch windows complement the suite. Extensive Macro support allows you to add even more power to this rich and yet intuitive man-machine interface.

Complex Events

Complex Event is a set of conditions that qualify 80196 emulation Breakpoints, Event Sequencer, or trace filtering in real-time. There are 5 complex events that may be qualifie the:

  • 64K/256K address match space;
  • 8/16-bit Data match;
  • RD, WR, INT, instruction fetch;
  • 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 80196 emulator Event or Pass Counter.

Breakpoints

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

  • Address or Range of Addresses;
  • Complex Events;
  • External Input;
  • Pass Counters;
  • Sequencer;
  • Trace Buffer Full Condition.

Trace Buffer

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 while executing. Trace will store up to 32 K samples comprised of the following:

  • Address Bus;
  • Data Bus;
  • Control signals;
  • I/O pins;
  • Real Time Clock Stamp;
  • 8-ch. user logic state analyzer.

The trace can be collected selectively with the use of complex events. After capture it may be post-filtered using a variety of options from the trace filtering 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, using only one event. The trace contents may be viewed during program execution without stopping or slowing down the microcontroller.
