Description
ORCA Foundry Development System
The ORCA Foundry development system is used to
process a design from a netlist to a configured FPGA.
This system is used to map a design onto the ORCA
architecture and then place and route it using ORCA
Foundry’s timing-driven tools. The development system
also includes interfaces to, and libraries for, other popu-
lar CAE tools for design entry, synthesis, simulation,
and timing analysis.
The ORCA Foundry development system interfaces to
front-end design entry tools and provides the tools to
produce a configured FPGA. In the design flow, the
user defines the functionality of the FPGA at two points
in the design flow: at design entry and at the bit stream
generation stage.
Following design entry, the development system’s map,
place, and route tools translate the netlist into a routed
FPGA. A static timing analysis tool is provided to deter-
mine device speed, and a back-annotated netlist can
be created to allow simulation.

(continued)
Timing and simulation output files from ORCA Foundry
are also compatible with many third-party analysis
tools. Its bit stream generator is then used to generate
the configuration data, which is loaded into the FPGA’s
internal configuration RAM.
When using the bit stream generator, the user selects
options that affect the functionality of the FPGA. Com-
bined with the front-end tools, ORCA Foundry pro-
duces configuration data that implements the various
logic and routing options discussed in this product
brief.
