DLA Land and Maritime performs an intensive search to locate original parts, reviews QML/QVL and solicits SIA for commercial availability (details). Depending on whether you are a commercial or government contractor, there are several ways to obtain emulation devices.
Through logistics channels:
- Requisitions to DLA Land and Maritime
- DLA Managed NSNs
For MILSVC funded requirements:
- Military Interdepartmental Purchase Request (MIPR) to DLA
- SOW/RFP Prepared and Coordinated by DLA
By direct contract with SRI:
- Applies to non-government and commercial activities
- Contract arrangements between SRI and customer
- DLA Land and Maritime GEM Program Office verifies the device is obsolete
- Contacts the original manufacturers and aftermarkets who are members of the Semiconductor Industry Association (SIA) to ensure there is no commercial source
- Attempts to locate original parts from reputable distributors
Emulated devices are designed and fabricated on demand. For a routine, +5 V logic family device, turn-around time to deliver fully mil-screened parts part is about 6 months after order acceptance. For more complex ASICs lead time could take a year or longer. If we have residual assets on hand, we can typically ship product in two weeks or less.
Below is a table of ideal requirements for a new Emulation design. In general the more documentation that is available the better however with SRI’s reverse engineering capability design data can be regenerated from the actual microcircuit. Know-good sample part are essential for all new designs.
