CoolRunner/XPLA Professional Simulator:	What does the "Bitmap allocation error. Possible
too many signals" mean?



Problem Description:
Urgency: Standard

General Description: What does the simulation error: "Bitmap
allocation error. Possible too many signals" mean?


Solution 1:

The simulator error "Bitmap allocation error. Possible too many signals" has
to do with the video resources and the number of colors selected on
the machine.

For example, this could appear in a pz3960 simulation with about 300
signals shown and a large number of colors were selected
for the machine's video. This could cause the simulator to not open
reporting the above error. By setting the machine's video to 256 colors,
the error will disappear as well as permitting the simulator to run faster.

To change your machine's number of video colors, follow the steps below:

    1. Open the Control Panel window and click on the Display icon.
    2. Under the Settings tab, you will see a list box called Color Palette.
    3. Choose the color setting with 256 colors.
    4. Push the OK button.
