Forum Discussion
The simulation with default video timing looked great to me - it looks very solid. No issue with the simulation - it looks much better in the design example from Quartus 25.3. It is a very long sim so I didn't run to completion - I stopped it after about 1/2 hour but it looks very good.
My remaining concern is about generating video timing IP parameters for an 800x600 display. If you have any informal equations to copy & paste into the forum - that would be great. As I mentioned, the params generated by chatGPT were not acceptable to Quartus 25.3 when attempting to generate the IP design example.
You didn't explicitly say that the parameters in your screen shots above will work for an SVGA display - but I can try it. I will use what you provided to proceed through the whole build process.
FYI/for what it's worth - simulating the MIPI DSI-2 design example from Q25.3 also passed for me.

Hi SteveS109 ,
Glad that it work.
FYI for v25.1.1 there will be no warning for any calculation error for the Htotal and Hbend.
While in 25.3 onwards, once the value is not fit, there will be an error or warning message come out.
To fix this, I will file and KDB and internally we are preparing a patch (to tune the default value of Example design into working value - Subject to change).
Let me know if there is anything else I can help you out, please accept my apology for the delay of support due to forum migration, thanks for reaching me back. Wish you have a great day with your cat

Thank you - we look forward to receiving KDB information and patch.
In the meantime, it would help to have a blackbox IP component that could just be instantiated with Platform Designer as a placeholder. Is that something that you can easily supply or provide guidance on how to generate? We only need the MIPI DSI2 TX.
