New Contributorcvo not outputting separate syncs
Hi I am new to this site. I have a cyclone V and am trying to drive both a LCD and VGA using the CVO out. I have set the CVO to separate syncs. The LCD (640x480) kind of works, DE signal to LCD sync structure is incorrect and the separate H and Vsync outputs are inactive.
Is there anything in the CV GUI that could keep separate sync option off?
Thanks.

Hi,
As I understand it, you have some inquiries related to the CV CVO with separate sync. To facilitate further debugging, just would like to check with you on the following:
- Just wonder if you have had a chance to try with Modelsim simulation to see if can replicate similar observation? This could help to isolate any functional issue prior to hardware testing.
- To ease the debugging, I would recommend you to start with simple design ie TPG -> CVO in simulation.
- What is the Quartus version that you are using?
Please let me know if there is any concern. Thank you.
gweitzmanHi,
where can I find an example of TPG->CVO to simulate?

Hi,
Regarding your inquiry on the simulation example, for your information, you can create a simple Qsys system with TPG -> CVO with your targeted configuration. Then go to Generate -> Generate Testbench System. You can then further customize the test bench ie connecting the clocks according and the run through Modelsim simulation.
Please let me know if there is any concern. Thank you.

Hi,
I am almost there. Generated the TB and successfully compiled but couldn't simulate.
here are some of the errors:

Hi,
Still having problems. Tried to simulate and here is the latest error list.
