Mentor Graphics - EDA Technology

Mentor Graphics is a technology leader in electronic design automation (EDA), providing software and hardware design solutions that enable companies to develop better electronic products faster and more cost-effectively.

The company offers innovative products and solutions that help engineers overcome the design challenges they face in the increasingly complex worlds of board and chip design.

EZwave can analyze time or frequency domain waveform of any type: analog, digital, eye diagram, smith chart, polar or complex chart, and histogram. "

CompuPhase articles and Application notes

Termite Terminal - RS232 Interfacing - CompuPhase

Termite is an easy to use and easy to configure RS232 terminal. It uses an interface similar to that of "messenger" or "chat" programs, with a large window that contains all received data and an edit line for typing in strings to transmit. This terminal ought to help serial port SBC development.

Plug-in interface for pre-processing or alternative views of the data, logging received data to a file, adding a toolbar to Termite, and other functionality that you may think of.

It can also do ..
  • A history of commands that you typed, with auto-completion.
  • Support for non-standard Baud rates (MIDI, DMX512).
  • Data can be forwarded between two RS232 ports.

SDCC - Small Device C Compiler

SDCC was written by Sandeep Dutta and released under a GPL license. SDCC is a retargettable, optimizing ANSI - C compiler that works for the Intel 8051, Maxim 80DS390, Zilog Z80 and the Motorola 68HC08 based MCUs.

SDCC - Small Device C Compiler

Work is in progress on supporting the Microchip PIC16 and PIC18 series. SDCC is Free Open Source Software.

SDCC - Small Device C Compiler
  • ASXXXX and ASLINK, a Freeware, retargettable assembler and linker.
  • extensive MCU specific language extensions, allowing effective use of the underlying hardware.
  • a host of standard optimizations such as global sub expression elimination, loop optimizations (loop invariant, strength reduction of induction variables and loop reversing ), constant folding and propagation, copy propagation, dead code elimination and jump tables for 'switch' statements.
  • MCU specific optimizations, including a global register allocator.
  • adaptable MCU specific backend that should be well suited for other 8 bit MCUs
  • independent rule based peep hole optimizer.
  • a full range of data types: char (8 bits, 1 byte), short (16 bits, 2 bytes), int (16 bits, 2 bytes), long (32 bit, 4 bytes) and float (4 byte IEEE).
  • the ability to add inline assembler code anywhere in a function.
  • the ability to report on the complexity of a function to help decide what should be re-written in assembler.
  • a good selection of automated regression tests.
