Power-On Requirements
Spartan-IIE FPGAs require that a minimum suppl y current
ICCPO be provided to the VCCINT lines for a successful
power-on. If more current is available, the FPGA can con-
sume more than ICCPO min., though this cannot adversely
affe c t r e l iabi lity.
A maximum limit for ICCPO is not specified. Be careful when
using foldback/crowbar suppli es and fuses. It is possible to
control the magnitude of ICCPO by limiting the supply current
av ailable to the FPGA. A current limit below the trip lev el will
avoid inadvertently activating over-current protection cir-
cuits.
DC Input and Output Levels
Values for VIL and VIH are recommended input voltages.
Values for VOL and VOH are guaranteed output voltages
over t he recom men ded operating conditions. Only sele cted
standards are tested. These are chosen to ensure that all
standards meet their specifications. The selected standards
are tested at minimum VCCO with the respective IOL and IOH
currents shown. Other standards are sample tested.

Notes:

2. The ramp ti m e is measured from GND to 1.8V on a fully loaded boa rd.
3. VCCINT mus t not d ip i n the negative direction during power on.
4. Power -on current is measured with VCCINT and VCCO po wering up simul taneously.
5. I/Os ar e not guaran teed to be disabled until VCCINT is appli ed.

Switching Characteristics
Testing of switching parameters is modeled after testing
methods specified by MIL-M-38510/605. Internal timing
parameters are derived from measuring internal test pat-
terns. Listed below are representative values. For more
specific, more precise, and worst-case guaranteed data,
use the values reported by the static timing analyzer
(TRA CE in the Xilinx De v elopment System) and back -anno-
tated to the simulation netlist. All timing parameters assume
worst-case operating conditions (supply voltage and junc-
tion temperature). Values apply to all Spartan-IIE devices
unless otherwise noted.

DLL Timing Parameters
Switching parameters testing is modeled after testing meth-
ods specified by MIL-M-38510/605. Because of the difficulty
in directly measuring many internal timing parameters,
those parameters are derived from benchmark timing pat-
terns. The following guidelines reflect worst-case values
across the recom me nded operating conditions.
DLL Clock Tolerance, Jitter, and Phase Information
All DLL output jitter and phase specifications were deter-
mined through statisti cal mea suremen t at the package pins
using a clock mirror configuration and matched drivers.
Figure 1, pag e 1 4, provides def initions for various parame-
ters in the table below.

Notes:
1. Output Jitter is cycle-to-cycle jitter measured on the DLL outp ut clock, excluding input clo ck jitter.
2. Phase Offset between CLKIN and CLK O is t he worst-case fixed time difference between rising edges of CLKIN and CLKO,
excluding output jitter and input cloc k jitt er.

4. Maxim um Phase Differenc e bet ween CLKIN and CLK O i s the sum of output jit ter and p hase off set bet ween CLKIN and CLKO , or
the greatest difference bet ween CLKIN and CLKO rising edges due to DLL alone (excluding input clock jitter).
5. Maxim um Phase Difference betwe en Clock Outputs on the DLL is the sum of output jitter and phase offset between any DLL
