eX FPGA Architecture and Characteristics
1-26
Revision 10
Timing Characteristics
Timing characteristics for eX devices fall into three categories: family-dependent, device-dependent, and
design-dependent. The input and output buffer characteristics are common to all eX family members.
Internal routing delays are device-dependent. Design dependency means actual delays are not
determined until after placement and routing of the user’s design are complete. Delay values may then
be determined by using the Timer utility or performing simulation with post-layout delays.
Critical Nets and Typical Nets
Propagation delays are expressed only for typical nets, which are used for initial design performance
evaluation. Critical net delays can then be applied to the most timing critical paths. Critical nets are
determined by net property assignment prior to placement and routing. Up to six percent of the nets in a
design may be designated as critical.
Long Tracks
Some nets in the design use long tracks. Long tracks are special routing resources that span multiple
rows, columns, or modules. Long tracks employ three to five antifuse connections. This increases
capacitance and resistance, resulting in longer net delays for macros connected to long tracks. Typically,
no more than six percent of nets in a fully utilized device require long tracks. Long tracks contribute
approximately 4 ns to 8.4 ns delay. This additional delay is represented statistically in higher fanout
routing delays.
Timing Derating
eX devices are manufactured with a CMOS process. Therefore, device performance varies according to
temperature, voltage, and process changes. Minimum timing parameters reflect maximum operating
voltage, minimum operating temperature, and best-case processing. Maximum timing parameters reflect
minimum operating voltage, maximum operating temperature, and worst-case processing.
