APEX 20KC Programmable Logic Device Data Sheet
After an APEX 20KC device has been configured, it can be reconfigured
in-circuit by resetting the device and loading new data. Real-time changes
can be made during system operation, enabling innovative reconfigurable
computing applications.
APEX 20KC devices are supported by the Altera Quartus II development
system, a single, integrated package that offers HDL and schematic design
entry, compilation and logic synthesis, full simulation and worst-case
timing analysis, SignalTap logic analysis, and device configuration. The
Quartus II software runs on Windows-based PCs, Sun SPARCstations,
and HP 9000 Series 700/800 workstations.
The Quartus II software provides NativeLink interfaces to other industry-
standard PC- and UNIX workstation-based EDA tools. For example,
designers can invoke the Quartus II software from within third-party
design tools. Further, the Quartus II software contains built-in optimized
synthesis libraries; synthesis tools can use these libraries to optimize
designs for APEX 20KC devices. For example, the Synopsys Design
Compiler library, supplied with the Quartus II development system,
includes DesignWare functions optimized for the APEX 20KC
architecture.
Functional
Description
APEX 20KC devices incorporate LUT-based logic, product-term-based
logic, and memory into one device on an all-copper technology process.
Signal interconnections within APEX 20KC devices (as well as to and from
device pins) are provided by the FastTrack interconnect—a series of fast,
continuous row and column channels that run the entire length and width
of the device.
Each I/O pin is fed by an I/O element (IOE) located at the end of each row
and column of the FastTrack interconnect. Each IOE contains a
bidirectional I/O buffer and a register that can be used as either an input
or output register to feed input, output, or bidirectional signals. When
used with a dedicated clock pin, these registers provide exceptional
performance. IOEs provide a variety of features, such as 3.3-V, 64-bit,
66-MHz PCI compliance; JTAG BST support; slew-rate control; and
tri-state buffers. APEX 20KC devices offer enhanced I/O support,
including support for 1.8-V I/O, 2.5-V I/O, LVCMOS, LVTTL, LVPECL,
3.3-V PCI, PCI-X, LVDS, GTL+, SSTL-2, SSTL-3, HSTL, CTT, and 3.3-V
AGP I/O standards.
