Configuration Scheme
During initialization, which occurs immediately after configuration, the
device resets registers, enables I/O pins, and begins to operate as a logic
device. Before and during configuration, all I/O pins (except dedicated
inputs, clock, or configuration pins) are pulled high by a weak pull-up
resistor. Together, the configuration and initialization processes are called
command mode; normal device operation is called user mode.
SRAM configuration elements allow ACEX 1K devices to be reconfigured
in-circuit by loading new configuration data into the device. Real-time
reconfiguration is performed by forcing the device into command mode
with a device pin, loading different configuration data, re-initializing the
device, and resuming user-mode operation. The entire reconfiguration
process requires less than 40 ms and can be used to reconfigure an entire
system dynamically. In-field upgrades can be performed by distributing
new configuration files.
Configuration Schemes
The configuration data for an ACEX 1K device can be loaded with one of
five configuration schemes (see
application. An EPC16, EPC2, EPC1, or EPC1441 configuration device,
intelligent controller, or the JTAG port can be used to control the
configuration of a ACEX 1K device, allowing automatic configuration on
system power-up.
Multiple ACEX 1K devices can be configured in any of the five
configuration schemes by connecting the configuration enable (nCE) and
configuration enable output (nCEO) pins on each device. Additional
APEX 20K, APEX 20KE, FLEX 10K, FLEX 10KA, FLEX 10KE, ACEX 1K,
and FLEX 6000 devices can be configured in the same serial chain.
