Axcelerator Family FPGAs

With the Designer software, a user can lock the design

pins before layout while minimally impacting the results

of place-and-route. Additionally, Actel’s back-annotation

flow is compatible with all the major simulators and the

simulation results can be cross-probed with Silicon

Explorer II, Actel’s integrated verification and logic

analysis tool. Another tool included in the Designer

software is the SmartGen core generator, which easily

creates popular and commonly used logic functions for

implementation into your schematic or HDL design.

Actel's Designer software is compatible with the most

popular FPGA design entry and verification tools from

EDA vendors, such as Mentor Graphics, Synplicity,

Synopsys, and Cadence Design Systems. The Designer

software is available for both the Windows and UNIX

operating systems.

Programming

Programming support is provided through Actel's Silicon

Sculptor II, a single-site programmer driven via a PC-

based GUI. In addition, BP Microsystems offers multi-site

programmers that provide qualified support for Actel

devices. Factory programming is available for high-

volume production needs.

In-System Diagnostic and Debug

Capabilities

The Axcelerator family of FPGAs includes internal probe

circuitry, allowing the designer to dynamically observe

and analyze any signal inside the FPGA without disturbing

normal device operation. Up to four individual signals can

be brought out to dedicated probe pins (PRA/B/C/D) on

the device. The probe circuitry is accessed and controlled

via Silicon Explorer II (Figure 1-9), Actel's integrated

verification and logic analysis tool that attaches to the

serial port of a PC and communicates with the FPGA via

the JTAG port (See "Silicon Explorer II Probe Interface"

on page 2-91).

Summary

Actel’s

Axcelerator

family

FPGAs

extends

the

successful SX-A architecture, adding embedded RAM/

FIFOs, PLLs, and high-speed I/Os. With the support of a

suite of robust software tools, design engineers can

incorporate high gate counts and fixed pins into an

Axcelerator design yet still achieve high performance

and efficient device utilization.
