5.6.4. Programmable Current Strength
You can use the programmable current strength to mitigate the effects of high signal attenuation that is caused by a long transmission line or a legacy backplane.

Default current strength setting in the Intel® Quartus® Prime software:
- All non-voltage referenced I/O standards—50–Ω OCT without calibration
- SSTL Class I and HSTL Class I I/O standards—50–Ω OCT without calibration
- SSTL Class II and HSTL Class II I/O standards—25–Ω OCT without calibration
Programmable current strength is not available if you use RS OCT.
Note: Intel recommends that you perform IBIS or SPICE simulations to determine the best current strength setting for your specific application.
