Why does the simulation of the MIPI DSI-2 FPGA IP Design Example fail with default timing parameter settings?

Description

Due to a problem in the Quartus® Prime Pro Edition software version 25.1.1, users may observe the following error when simulating the MIPI DSI-2 FPGA IP Design Example using the default video timing parameter settings.

Fatal: dsi2_ed_sim_tb.dut.dsi2_tx.dsi2_tx.dsi2.mipi_dsi2_tx_inst.<protected>.<protected>: Error: axis_m does not accept back pressure

Resolution

To work around this problem in the Quartus Prime Pro Edition software version 25.1.1, update the video paramaters as below :
 

Dimension:

Default value for HTOTAL: 2176

Default value for VTOTAL: 100

Blank Timing:

Default value for HB_END: 2048

Default value for V1B_START: 0

Default value for V1B_END: 4

Syn Timing

Default value for HS_START: 52

Default value for HS_END: 100

Default value for V1S_VSTART: 2

Default value for V1S_HSTART: 52

Default value for V1S_VEND: 3 

Default value for V1S_HEND: 52

This problem is fixed beginning with the Quartus Prime Pro Edition software version 25.3.
