Predictable Performance: Tight
Delay Distributions
Propagation delay between logic modules depends on
the resistive and capacitive loading of the routing tracks,
the interconnect elements, and the module inputs being
driven. Propagation delay increases as the length of
routing tracks, the number of interconnect elements, or
the number of inputs increases.
From a design perspective, the propagation delay can be
statistically correlated or modeled by the fanout
(number of loads) driven by a module. Higher fanout
usually requires some paths to have longer routing
tracks.
The MX FPGAs deliver a tight fanout delay distribution,
which is achieved in two ways: by decreasing the delay of
the interconnect elements and by decreasing the number
of interconnect elements per path.
Actel’s patented antifuse offers a very low resistive/
capacitive interconnect. The antifuses, fabricated in
0.45 lithography, offer nominal levels of 100
resistance and 7.0 femtofarad (fF) capacitance per
antifuse.
MX fanout distribution is also tight due to the low
number of antifuses required for each interconnect path.
The proprietary architecture limits the number of
antifuses per path to a maximum of four, with
90 percent of interconnects using only two antifuses.
Timing Characteristics
Device timing characteristics fall into three categories:
family-dependent,
device-dependent,
and
design-
dependent. The input and output buffer characteristics
are common to all MX devices. Internal routing delays
are device-dependent. Design dependency means actual
delays are not determined until after place-and-route of
the user’s design is complete. Delay values may then be
determined by using the Timer tool in the Designer
software or by performing simulation with post-
layout delays.
Critical Nets and Typical Nets
Propagation delays in this datasheet apply to 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 in Actel's Designer software
prior to placement and routing. Up to 6% of the nets in
a design may be designated as critical.
Long Tracks
Some nets in the design use long tracks, which are
special routing resources that span multiple rows,
columns, or modules. Long tracks employ three and
sometimes four antifuse connections, which increase
capacitance and resistance, resulting in longer net delays
for macros connected to long tracks. Typically, up to
6 percent of nets in a fully utilized device require long
tracks. Long tracks add approximately a 3 ns to a 6 ns
delay, which is represented statistically in higher fanout
(FO=8) routing delays in the datasheet specifications
section beginning on page 1-16.
Timing Derating
MX 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.
