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.
