Preserving Your JTAG Emulator Investment!

When Do I Need a New JTAG Emulator?

STAFFORD, TX. (September 29, 2017) – You’ve completed a design project with a Texas Instruments processor and now you are on to another project with a TI processor.

Can you use the same JTAG Emulator ? i.e. Do I need to buy on another emulator ($$$) ?

The answer is: it depends. What does it depend on?

a: the type of the new processor

You may be moving from one type of processor to another which requires different capabilities. The new processor may use CJTAG or an ARM header. If your current emulator doesn’t support CJTAG the solution is to purchase another emulator which does support CJTAG. If a standard ARM header is required then an adapter may be the solution.

b. the JTAG header selected on the new board layout

Your new board may have space requirements meaning a smaller header is required. In this case the solution is an adapter to convert the pinnings of the old JTAG Emulator to the header in the new board. Spectrum Digital has over 20 different types of adapters to help you.

c. the capability needed for the new JTAG Emulation

You may be moving from a mircontroller to a multicore device. This means the amount of code you will be downloading will be much larger. The old emulator may have worked well for the small code foot print in the microcontroller but when there is a lot of code you need better download speeds. You may want to upgrade to another higher performing emulator.

If your new processor is a new low power microcontroller you may want power monitoring capability. It may require a new emulator since the old emulator didn’t have the capability.

If you have a high end multicore device you may need trace capability to tune the code and system performance. Here again a new emulator may be required.
