DESIGN DEVELOPMENT TOOLS
SNAP
The SNAP Software Development System
provides the necessary tools for designing
with PML. SNAP provides the following:
• Schematic entry netlist generation from
third-party schematic design packages
such as OrCAD/SDT III™ and
FutureNet™.
• Macro library for standard TTL functions
and user defined functions
• Boolean equation entry
• State equation entry
• Syntax and design entry checking
• Simulator includes logic simulation, fault
simulation and timing simulation.
SNAP operates on an IBM® PC/XT, PC/AT,
PS/2, or any compatible system with DOS
2.1 or higher. The minimum system
configuration for SNAP is 640K bytes of RAM
and a hard disk.
SNAP provides primitive PML function
libraries for third-party schematic design
packages. Custom macro function libraries
can be defined in schematic or equation form.
After the completion of a design, the software
compiles the design for syntax and
completeness. Complete simulation can be
carried out using the different simulation tools
available.
The programming data is generated in
JEDEC format. Using the Device
Programmer Interface (DPI) module of SNAP,
the JEDEC fusemap is sent from the host
computer to the device programmer.
DESIGN SECURITY
The PLHS501 has a programmable security
fuse that controls the access to the data
programmed in the device. By using this
programmable feature, proprietary designs
implemented in the device cannot be copied
or retrieved.
