Problem with Pin assignment Cyclone V Quartus v13.1 - Critical Warning (169244):

Question

Have this error occurring

Critical Warning (169244): Total number of single-ended output or bi-directional pins in bank 3A have exceeded the recommended amount in a bank where dedicated LVDS, RSDS, or mini-LVDS outputs exists.

Also for 2 other banks, however there are no LVDS, RSDS or mini-LVDS inputs or outputs on the banks that bring up this error (but there are on my design on different banks)

Does anyone have a solution to this problem?

I am afraid, you are totally alone with your problem. Only Quartus II 13.0 SP1 is available at the moment for regular users.

See the altera quartus online help for your answer:

This is not a Cyclone V related problem. Be careful if you create a custom FPGA pin-out: one FPGA bank has a common I/O standard. Replace some output / bidir pins with input pins coming from an other FPGA bank.

What's the info message under the critical warning? Did you tried I/O toggle rate assignment for the "slow" pins of your design? Be aware of this: http://www.altera.com/support/kdb/solutions/rd07082013_903.html

Might be worth trying but my bank is not so highly populated, also it does not line up with the error message. (The help offered does line up with the error reported but the reported error does not line up with the design entered.) Thank you.
