CODE FILE

Shown in Figure 3 (below) is the software design flow for a PSD5XX device.

PSDsoft—WSI’s software development suite—is used throughout the design phase. You

start with a design file that is written in PSDabel-a high-level hardware description language

(HDL). Before you compile your design, you must also configure the PSD5XX so it knows

what signals to expect from your microprocessor and what pre-runtime options should be

set (such as the security bit).

Once you have a design file and have configured the device, you are ready to run the Fitter

and Address Translator. The Fitter accepts input from PSDabel and PSD Configuration,

synthesizes this user logic and configuration, and fits the design to the PSD silicon.

The Address Translator process allows the user to map the MCU firmware from a

cross-compiler (in Intel HEX or S-Record format) into the NVM memory blocks within the

PSD. As a result, the MCU firmware is merged with the logic and configuration definition of

the PSD.

The output of the Address Translator and the Fitter is the required object file that is used by

a programmer to program the PSD device. The object file includes chip configuration, the

PLD fusemap, and MCU firmware information.

PSDsilosIII is an optional program that provides functional chip-level simulation of the

PSD5XX. PSDsoft automatically creates files for input to the simulator. These files convey

relevant design information to the simulator. As a result, the user only has to create a stim-

ulus file since all of the signals and node names are taken from the design file.
