AN 91: Understanding FLEX 10K Timing
External Timing
Parameters
External timing parameters represent actual pin-to-pin timing
characteristics. Each external timing parameter consists of a combination
of internal delay elements. They are worst-case values, derived from
extensive performance measurements, and are ensured by device testing
or characterization. All external timing parameters are shown in bold
type. For example,
t
DRR
is the AC operating specification. Other external
timing parameters can be estimated by using the timing model or the
equations in
“Calculating Timing Delays” on page 884
of this application
note.
t
DRR
Register-to-register delay. The time required for the signal
from one register to pass through four LEs via three row
interconnects and four local interconnects to reach the
D
input of a second register. The test circuit used for this
parameter is a register with an output that goes through
three
LCELL
primitives in two different LABs; the last
LCELL
feeds another register in another LAB.
Figures 1

show this path for different FLEX 10K devices. The test
circuit files are available from Altera Applications.
