Simultaneously Switching Outputs
Due to package electrical parasitics, a given package supports a limited number of simultaneous switching outputs (SSOs)
when using fast, high-drive outputs. Table 33 and Table 34 provide guidelines for the recommended maximum allowable
number of 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, Table 33 provides the number of equivalent VCCO/GND pairs per bank. For each
output signal standard and drive strength, Table 34 recommends the maximum number of SSOs, switching in the same
direction, allowed per VCCO/GND pair within an I/O bank. The guidelines are categorized by package style, slew rate, and
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 Table 34 is greater than the maximum
I/O per pair in Table 33, then there is no SSO limit for the exclusive use of that I/O standard.
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 inductance introduced by the socket, the SSO values do not apply for
FPGAs mounted in sockets. The SSO values assume that the VCCAUX is powered at 3.3V. Setting VCCAUX to 2.5V provides
better SSO characteristics. For more detail, see UG381: Spartan-6 FPGA SelectIO Resources User Guide.
