•
Program the software modules. Desk-check each module as it is completed. Name and
store the software modules as files in the development system's memory. Assemble or
compile the modules. Link and load the combinations that are ready to be tested.
•
Emulate the program using an emulator to debug the software.
Hardw are/Softw are Integration
When the hardware and software designs are complete, system integration is already in pro
gress. The usefulness of a development system with an emulator extends into the integration
and test phases.
When an emulator is connected to the prototype system through the microprocessor socket and
emulator hardware probes, the emulator can emulate, test, and trace prototype system
operation.
After testing the prototype, the host development system with an emulator can be used to verify
the product in production test. Test procedures developed for final prototype testing can serve
as the basis for production test routines. The same procedures developed for hardware debug
ging and production test can also be used to troubleshoot and repair failing products at a repair
center.
An Introduction to the l
Intel developed the PICE system to address the requirements of designers who use Intel's iAPX
microprocessors. The PICE system is a second-generation design tool that provides the follow
ing advantages:
•
Full-speed, multiple microprocessor emulation
•
Real-time emulation support for each of the iAPX microprocessors (86/88, 186/188, and
286)
•
Software patching without recompiling or reassembling
•
Extensive breakpoint capabilities
•
Expanded logic analysis
The PICE system also offers the following features:
•
Access to eight signals input from the prototype system and two signals output to the
prototype system using the emulation clips. An additional output line is asserted when the
PICE system breaks emulation, and another is asserted when the PICE system triggers a
trace. •
•
An optional Intel Logic Timing Analyzer (iLTA) module which is a general-purpose,
integrated, 16-channel, 100-MHz logic timing analyzer. With the mass storage provided
by the host development system, you can store an unlimited number of scope displays for
later analysis. Combined with the capabilities of the PICE system, the iLTA extends the
range of development applications. [This option is not available for IBM PC hosts.]
