How do I estimate the current drive strength of the I/O buffer when using series on-chip termination (OCT)? - How do I estimate the current drive strength of the I/O buffer when using series on-chip termination (OCT)? Description Many Intel® FPGAs have output pin configuration options which allow you to select either current drive strength or series on chip termination (OCT). Although these have different settings in the Intel Quartus® Prime software, they use the same structures in the output buffer to implement the desired setting. Download this How-To document to learn how you can use IBIS models to estimate the current strength of the series OCT settings.
