When the model starts, the Foundation Platform CLCD window opens, representing the contents of the simulated color LCD frame buffer. It automatically resizes to match the horizontal and vertical resolution set in the CLCD peripheral registers.
The following figure shows the Foundation Platform CLCD in its default state, immediately after being started:
The top section of the CLCD window displays the following status information:
A counter showing the total elapsed time, in seconds.
This is wall clock time, not simulated time.
This option limits the rate of simulated time when the cores are in WFI, reset, or otherwise idle. Simulation time is restricted so that it more closely matches real time.
Rate Limit is disabled by default. Click the square button to enable it. The text changes from OFF to ON and the colored box becomes lighter red when the Rate Limit is enabled.
--(no-)rate-limitparameter when instantiating the model.
Shows the number of instructions executed per second of wall clock time.
Icons to represent different processor states.
The following table shows each of the possible icons:
Table 3-7 Core run state icon descriptions
||Run status unknown, that is, simulation has not started.|
||The core is running, is not idle, and is executing instructions.|
||An external halt signal is asserted.|
||The last instruction executed was WFE, and standby mode has been entered.|
||The last instruction executed was WFI and standby mode has been entered.|
||An external reset signal is asserted.|
||Partial core power down.|
||Complete core power down.|
The large area at the bottom of the window displays the contents of the CLCD buffer. The following figure shows this:
You can hide the host mouse pointer by pressing the Left Ctrl+Left Alt keys. Press the keys again to redisplay the host mouse pointer. Only the Left Ctrl key is operational. The Ctrl key on the right-hand side of the keyboard does not have the same effect.
