good in-circuit emulator

To your experience, which 8051 in circuit emulator is giving faithful result, yet low cost (<$10K)? I am using Philips 8xC58 family microcontrollers. Thanks.

  • The first consideration should be: do you want a bondout emulator (e.g. Philips, Nohau) or a non-bondout emulator such as CEIBO.

    A bondout emulator allow a few more things than a non-bondout and usually is a bit faster in the response to the keyboard (same response to a breakpoint). The more expensive bondout ICEs has some very nice trace features. Also a bondout typically does not interfere with your code space and stack.

    A non-bondout emulator require that you leave a bit of code memory (typ about 1k) free and will grab 2-5 stack positions. A non-bondout will not have very advanced trace if any.

    This makes the bondout the ICE of choice except for one thing: With a bondout you need to buy a 'pod' ($200- $2000) for every derivative you want to emulate with a non-bondout, you just pop the other derivative in (chip cost $2-$20).
