Virtex-5 Electrical Characteristics
Virtex™-5 FPGAs are available in -3, -2, -1 speed grades,
with -3 having the highest performance.
Virtex-5 DC and AC characteristics are specified for both
commercial and industrial grades. Except the operating
temperature range or unless otherwise noted, all the DC
and AC electrical parameters are the same for a particular
speed grade (that is, the timing characteristics of a -1 speed
grade industrial device are the same as for a -1 speed grade
commercial device). However, only selected speed grades
and/or devices might be available in the industrial range.
All supply voltage and junction temperature specifications
are representative of worst-case conditions. The parame-
ters included are common to popular designs and typical
applications.

Important Note
Typical values for queiscent supply current are now specified at nominal voltage, 85ºC junction temperatures (Tj). Xilinx
recommends analyzing static power consumption at Tj = 85ºC because the majority of designs operate near the high end of
the commercial temperature range. Data sheets for older products (e.g., Virtex-4 devices) still specify typical quiescent
supply current at Tj = 25ºC. Queiscent supply current is specified by speed grade for Virtex-5 devices. Use the XPOWER™
Estimator (XPE) spreadsheet tool (download at http://www.xilinx.com/power) to calculate static power consumption for
conditions other than those specified in Ta bl e 4.

Power-On Power Supply Requirements
Xilinx FPGAs require a certain amount of supply current
during power-on to insure proper device initialization. The
actual current consumed depends on the power-on ramp
rate of the power supply.
The power supplies can be can be turned on in any
sequence, though the specifications shown in Ta bl e 5 are
for the recommended power-on sequence of VCCINT
,
VCCAUX, and VCCO. Xilinx does not specify the current for
other power-on sequences.
Table 5 shows the minimum current required by Virtex-5
devices for proper power-on and configuration.
If the current minimums shown in Tabl e 5 are met, the
device powers on properly after all three supplies have
passed through their power-on reset threshold voltages.
The FPGA must be configured after VCCINT is applied.
Once initialized and configured, use the XPOWER tools to
estimate current drain on these supplies.

Notes:
1. Typical values are specified at nominal voltage, 85°C junction temperatures (Tj). Industrial(I) grade devices have the same typical values as
commercial (C) grade devices at 85°C, but higher values at 100°C. Use the XPE tool to calculate 100°C values.
2. Typical values are for blank configured devices with no output current loads, no active input pull-up resistors, all I/O pins are 3-state and floating.
3. If DCI or differential signaling is used, more accurate quiescent current estimates can be obtained by using the XPOWER Estimator (XPE) or
XPOWER Analyzer (XPA) tools.

Switching Characteristics
All values represented in this data sheet are based on
speed specification version 1.57. Switching characteristics
are specified on a per-speed-grade basis and can be desig-
nated as Advance, Preliminary, or Production. Each desig-
nation is defined as follows:
Advance
These specifications are based on simulations only and are
typically available soon after device design specifications
are frozen. Although speed grades with this designation are
considered relatively stable and conservative, some
under-reporting might still occur.
Preliminary
These specifications are based on complete ES (engineer-
ing sample) silicon characterization. Devices and speed
grades with this designation are intended to give a better
indication of the expected performance of production sili-
con. The probability of under-reporting delays is greatly
reduced as compared to Advance data.
Production
These specifications are released once enough production
silicon of a particular device family member has been char-
acterized to provide full correlation between specifications
and devices over numerous production lots. There is no
under-reporting of delays, and customers receive formal
notification of any subsequent changes. Typically, the slow-
est speed grades transition to Production before faster
speed grades.
All specifications are always representative of worst-case
supply voltage and junction temperature conditions.
Since individual family members are produced at different
times, the migration from one category to another depends
completely on the status of the fabrication process for each
device.
Table 28 correlates the current status of each Virtex-5
device on a per speed grade basis.
Testing of Switching Characteristics
All devices are 100% functionally tested. Internal timing
parameters are derived from measuring internal test pat-
terns. Listed below are representative values.
For more specific, more precise, and worst-case guaran-
teed data, use the values reported by the static timing ana-
lyzer and back-annotate to the simulation net list. Unless
otherwise noted, values apply to all Virtex-5 devices.

In some cases, a particular family member (and speed
grade) is released to production before a speed specifica-
tion is released with the correct label (Advance, Preliminary,

subsequent speed specification releases. Table 29 lists the
production released Virtex-5 family member, speed grade,

IOB Pad Input/Output/3-State Switching Characteristics
Table 30 summarizes the values of standard-specific data
input delay adjustments, output delays terminating at pads
(based on standard) and 3-state delays.
TIOPI is described as the delay from IOB pad through the
input buffer to the I-pin of an IOB pad. The delay varies
depending on the capability of the SelectIO input buffer.
TIOOP is described as the delay from the O pin to the IOB
pad through the output buffer of an IOB pad. The delay var-
ies depending on the capability of the SelectIO output
buffer.
TIOTP is described as the delay from the T pin to the IOB
pad through the output buffer of an IOB pad, when 3-state is
disabled. The delay varies depending on the SelectIO capa-
bility of the output buffer.
Table 31 summarizes the value of TIOTPHZ. TIOTPHZ is
described as the delay from the T pin to the IOB pad
through the output buffer of an IOB pad, when 3-state is
enabled (i.e., a high impedance state).

Notes:
1. Input delay measurement methodology parameters for LVDCI and HSLVDCI are the same as for LVCMOS standards of the same voltage.
Parameters for all other DCI standards are the same as for the corresponding non-DCI standards.
2. Input waveform switches between VLand VH.
3. Measurements are made at typical, minimum, and maximum VREF values. Reported delays reflect worst case of these measurements. VREF values
listed are typical.
4. Input voltage level from which measurement starts.
5. This is an input voltage reference that bears no relation to the VREF / VMEAS parameters found in IBIS models and/or noted in Figure 6.

Output Delay Measurements
Output delays are measured using a Tektronix P6245
TDS500/600 probe (< 1 pF) across approximately 4" of FR4
microstrip trace. Standard termination was used for all test-
ing. The propagation delay of the 4" trace is characterized
separately and subtracted from the final measurement, and
is therefore not included in the generalized test setup shown
in Figure 6.
Measurements and test conditions are reflected in the IBIS
models except where the IBIS format precludes it. Parame-
ters VREF , RREF , CREF , and VMEAS fully describe the test
conditions for each I/O standard. The most accurate predic-
tion of propagation delay in any given application can be
obtained through IBIS simulation, using the following
method:
1. Simulate the output driver of choice into the generalized
test setup, using values from Ta b l e 33.
2. Record the time to VMEAS .
3. Simulate the output driver of choice into the actual PCB
trace and load, using the appropriate IBIS model or
capacitance value to represent the load.
4. Record the time to VMEAS .
5. Compare the results of steps 2 and 4. The increase or
decrease in delay yields the actual worst-case
propagation delay (clock-to-input) of the PCB trace.

Notes:
1. Setup and Hold times are measured over worst case conditions (process, voltage, temperature). Setup time is measured relative to the Global Clock
input signal using the slowest process, highest temperature, and lowest voltage. Hold time is measured relative to the Global Clock input signal using
the fastest process, lowest temperature, and highest voltage.
2. IFF = Input Flip-Flop or Latch
3. A Zero "0" Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed "best-case", but if a "0" is listed,
there is no positive hold time.

Notes:
1. Setup and Hold times are measured over worst case conditions (process, voltage, temperature). Setup time is measured relative to the Global Clock
input signal using the slowest process, highest temperature, and lowest voltage. Hold time is measured relative to the Global Clock input signal using
the fastest process, lowest temperature, and highest voltage. These measurements include CLK0, DCM, CLKOUT0, PLL, and jitter.
2. IFF = Input Flip-Flop or Latch
3. Use IBIS to determine any duty-cycle distortion incurred using various standards.

Notes:
1. These parameters represent the worst-case duty cycle distortion observable at the pins of the device using LVDS output buffers. For cases where
other I/O standards are used, IBIS can be used to calculate any additional duty cycle distortion that might be caused by asymmetrical rise/fall times.
2. The TCKSKEW value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree skew exists
for I/O registers that are close to each other and fed by the same or adjacent clock-tree branches. Use the Xilinx FPGA_Editor and Timing Analyzer
tools to evaluate clock skew specific to your application.
