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
Approval to Bid
DLA Land and Maritime GEM Program Office verifies the device is obsolete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.
New Emulation Requirements
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.
