Table 31: Output Delay Measurement Methodology (Cont’d)
Simultaneously Switching Outputs
Due to lead inductance, a given package supports a limited number of simultaneous switching outputs (SSOs) when using
fast, high-drive outputs.
SSOs. These guidelines describe the maximum number of user I/O pins of an output signal standard that should
simultaneously switch in the same direction, while maintaining a safe level of switching noise for that particular signal
standard. Meeting these guidelines for the stated test conditions ensures that the FPGA operates free from the adverse
effects of GND and power bounce.
For each device/package combination,

output drive current. The number of SSOs are also specified by I/O bank. Multiply the appropriate numbers from each table
to calculate the maximum number of SSOs allowed within an I/O bank. The guidelines assume that all pins within a bank use
the same I/O standard. Exceeding these SSO guidelines can result in increased power or GND bounce, degraded signal
integrity, or increased system jitter. For a given I/O standard, if the SSO limit per pair in

The recommended maximum SSO values assume that the FPGA is soldered on a printed circuit board and that the board
uses sound design practices. Due to the additional lead inductance introduced by the socket, the SSO values do not apply
for FPGAs mounted in sockets. The SSO values assume that the V
provides better SSO characteristics. For more detail, see the Spartan-6 FPGA SelectIO Resources User Guide.
