It is also possible to store all bus cycles and then just look at selected cycles. This is called trace
filtering.
1.1.3
The E6000 emulator allows you to measure the total execution time, or to measure the time of
execution between specified events in the complex event system. You can set the resolution of the
timer to any of the following values:
20 ns, 125 ns, 250 ns, 500 ns, 1 µs, 2 µs, 4 µs, 8 µs, or 16 µs.
At 20 ns, the maximum time that can be measured is approximately six hours, and at 16 µs the
maximum time is about 200 days.
1.1.4
The E6000 emulator provides functions for measuring the performance of a program. The
performance of the specified program range can be displayed either as a histogram or in
percentage form. A timer resolution of 20 ns, 40 ns, or 160 ns can be selected. In addition, the
execution count of the specified program range can be measured (1 to 65535).
1.1.5
The E6000 emulator incorporates a bus monitoring function that monitors and displays the
contents of the accessed area in HDI windows without stopping the program execution. Up to
eight blocks of 256 bytes can be monitored. In addition, the E6000 emulator can output trigger
signals to external probe 2 (EXT2) when specified addresses (four points max.) are accessed.
1.1.6
The E6000 emulator provides a coverage function. The coverage function executes programs and
obtains and stores histories of data access. This function allows you to know what part of your
program has been or has not been tested.
1.2
In most practical debugging applications, the program or hardware errors that you are trying to
debug occur under a certain restricted set of circumstances. For example, a hardware error may
