Concurrent Programming: The Key to Fast Throughput and High Productivity

MultiWriter Programs Up to 384 Parts Simultaneously

As CPLD memory sizes increase, fast programming times are critically important.  MultiWriter delivers impressive throughput improvements over convention ICT-based part programming approaches via three key innovations:

  1. Serial-bus programming at near-data book speeds facilitated by MutliWriter’s unique in-fixture hardware that eliminates expensive channel cards and minimizes wire length for excellent signal fidelity.
  2. Concurrent programming of up to 384 identical chips at a time (crucial for multi-board panel assemblies).
  3. Concurrent programming of up to 16 different device types.  That means up to 384 (16 x 24) devices may be programmed concurrently.


The example multi-board panel assembly illustrated at right demonstrates how MultiWriter ccp multiplies thorughput compared to conventional ISP programming. 

A panel consisting of four identical boards, each with three different programmable parts (labeled A, B, C) requires 12 separate programming and verification operations using a conventional in-line ISP programmer.

Concurrent programming requires only a single program/ verification step that covers all twelve parts.

Multi-board panel: 4 boards, each with 3 different ISP chips
 
 

 

 

Each red box represents an individual programming/ verification operation. 

 
Conventional Part Programming: Requires 24 individual programming/verification steps conducted in sequence.
 
MultiWriter Concurrent Programming: Requires just one programming/ verification step since all chips are programmed and verified concurrently.

MultiWriter Concurrent Chip Programming Multiplies Productivity

  • High programming data speeds combined with concurrent chip programming speed throughput and increase productivity
  • Program up to 384 chips of up to 16 different types simultaneously at near data-book speeds
  • The ideal in-line programming solution for serial Flash, EEPROMs, embedded microcontrollers, and CPLDs/FPGAs
  • High signal integrity via short wire lengths is well-suited to today’s higher programming speed
  • Unified hardware architecture eliminates problems created by multi-vendor dongle-type solutions
  • At a substantially lower cost that in-line programming alternatives such as standalone device programmers and traditional in-circuit tester.

MultiWriter Concurrent Programming is available in the MultiWriter subsystem on the Analyst ems Low Cost In-circuit tester and on the standalone MultiWriter pps On-board Gang Programming System.
