Urgency: Standard

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

Solution

The simulator error "Bitmap allocation error. Possible too many signals"
relates to 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, where a large number of colors was selected for the
machine's video. This could cause the simulator not to open, generating
the above error. By setting the machine's video to 256 colors, the error
will disappear, and the simulator will be permitted 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. Click the OK button.
