Notes to
(1) Altera does not recommend M to exceed six inches as listed in
(2) Altera recommends using a balanced star routing. Try to keep the N length equal and as short as possible to minimize
Estimating the AP Configuration Time
AP configuration time is dominated by the time it takes to transfer data from the
parallel flash to the Cyclone III devices. This parallel interface is clocked by the
Cyclone III DCLK output (generated from an internal oscillator). As listed in
on page
20 MHz (50 ns). In word-wide cascade programming, the DATA[15..0] bus transfers
a 16-bit word and essentially cuts configuration time to approximately 1/16 of the AS
configuration time. Therefore, the maximum configuration time estimation for an
EP3C40 device (9,600,000 bits of uncompressed data) is defined in
Equation
Equation 9–4.
Equation 9–5.
To estimate a typical configuration time, use the typical DCLK period listed in
Table 9–8 on page
configuration time is 20 ms.
