There could be a number of situations where electronic hardware obsolescence is affecting your project or the system that you have either designed, maintained or perhaps you're redesigning to replace an old system, incorporating newer technology, more bandwidth.
Some of the issues that you will come up against are:
- Pin compatibility, either from an electronic board or system chassis.
- The technology has ceased to exist or will not exist soon.
- The backplane technology has insufficient bandwidth for new system requirements.
- An electronic board component has ceased to exist, with no other replacement available.
- A COTS provider has changed board designs or longer manufacture the board that you might use.
- The Operating System is no longer supported or a kernel change will not work with your drivers.
- The electronics hardware supplier has provided a new and different software library.
In the world of COTS providers there are standards for VME, cPCI, VXS, VME, ATCA, Micro TCA and others. However, there are no standards on how the boards and IO should be interconnected together. Therefore, most COTS vendor designs their chassis, processor and IO boards in a proprietory manner.
My next BLOG will look at how obsolescence issues might be analysed in order to find solutions for the future.
