1.8.1. GPIO SSO Estimator Tool for MAX® 10 FPGA Package B610

For the MAX® 10 FPGA package B610, the GPIO SSO Estimator tool calculates the SSO noise margin on a per bank basis, using the same structure for each I/O bank.

In the GPIO SSO Estimator Tool for MAX® 10 FPGA Package B610, set the parameter settings for the LVTTL/LVCMOS output or bidirectional pins in the marked areas, as shown in the following figure.

Figure 7.  GPIO SSO Estimator Tool for MAX® 10 FPGA Package B610 StructureThis figure shows the estimator structure for I/O bank 4.


Ensure that you set valid parameter settings. Otherwise, the corresponding Toggling Output I/O Counts cell remains blank and disabled. For example, in the preceding figure, the "fixed" current strength setting is only applicable to 1.0 V LVCMOS.
