Regular ContributorHello Moti,
May I know which version of Quartus are you using?
Try this workaround to solve Error 169029:
1. Remove the location assignment of pin_perst
2. Add a quartus.ini file in your project directory with: dft_skip_oct_vccn_check = on
Try this workaround to solve Error 169032
1. Assign 1.5V PCML I/O standard to Cyclone IV GX transceiver input pins.
Thank you.
New ContributorThanks AminT for the fast response.
the version is Quartus standard 19.1,
I added the quartus.ini file and define the clock pin as Sub-LVDS, the 2 error are gone ( 169029 & 169032 ).
what causes the error in Quartus ?
but still the question is technical, can I now connect to the Max10 differential clock (of 1.8V at bank of 1.8V
and there is no any Vref from the pins to the CPLD) and define it as LVDS ? Sub-LVDS ?
Do they require Vref ? and what with others differential I/O 's ?
Thank you
