• DCD-SEMI is an expert when it comes to solve the issue of obsolescence of formerly used components,
  • We can offer a 1:1 replacement for most popular architectures that are no longer available,
  • Having it provided as a HDL Source code, will make it valid, never obsolete and ready to use with any future technology,
  • DCD-SEMI mastered hundreds of designs for obsolete parts in various industrial applications like e.g. automotive, transportation, consumer electronics, household goods etc.
  • No matter when it comes to design for obsolete or standard IP Cores, DCD’s solutions are tailored to specific project needs – they also implement a wide set of peripherals to address a variety of possible applications,
  • DCD’s IP Cores might be used either as a replacement for an original architecture or as a main CPU in embedded 8/16/32-bit applications,
  • These cores have been used in numerous projects in such application areas as military electronics and industrial automation; these are also technology independent and therefore can be implemented in any ASIC or FPGA designs.

Case studies

DCD’s in its portfolio more than 70 different architectures, among them IP cores equivalent to obsolete chips that cover the following processors: 8-bit Zilog® Z80, 16-bit Motorola® 68000, Intel® 8050/80251 as well as clones of digital signal processors once manufactured by Texas Instruments®, Motorola® etc.

Among other customers who trusted DCD and ordered solutions for obsolete parts one can find e.g Caterpillar, Siemens and dozens of other (NDA).

Proper design flow is a key

Basic development steps in the creation of a virtual component include:

  1. Development of the macro specification
  2. Partitioning the macro into subblocks
  3. Development of a testing environment and a test suite
  4. Design and verification of subblocks
  5. Macro integration and final verification
  6. Prototyping the macro in FPGA
  7. Productization
