How to use OCT calibration modules on CYCLONE 10LP ?
- 7 years ago
Hi LLars1,
As I can see, there is no OCT IP core available for Cyclone 10 LP actually.
And I will try to explain why. If you will create an example project, for example for Cyclone V,
you will be able to include OCT IP core in your project. When I will suggest choosing
"Calibrate OCT on power-up" from MegaWizard GUI. You will see that all other options, in that case, will be disabled.
Now, if you look at Cyclone 10 LP datasheet (https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-10/c10lp-51002.pdf)
Table 8. Series OCT with Calibration at Device Power-Up Specifications for Intel Cyclone 10 LP Devices
you can read - "OCT calibration is automatically performed at device power-up for OCT-enabled I/Os."
So in your case, there is only one case for OCT calibration - at power-up, and there is, in that case, no need in IP core functionality.
You should just use assignment "Output termination" in assignment editor and choose "with Calibration".
Best regards,
Ivan
