THIS IS A COMBINED SOURCES SOUGHT NOTICE AND NOTICE OF INTENT TO SOLE SOURCE The National Institute of Standards and Technology (NIST) is seeking information from sources that may be capable of providing GDSFactory+ Software. If no alternate sources are identified, the Government intends to issue a Sole Source Award to Doplaydo Inc., 1650 Castro Street, Mountain View, CA 94041, under the authority of FAR 13.106–1(b). The North American Industry Classification System (NAICS) code for this acquisition is 541511, Custom Computer Programming Services, with a size standard of $34.0 M. The Office of Information Systems Management’s (OISM) Research Services Office (RSO) at NIST manages and supports NIST’s enterprise on and off premise computing and data storage environments that underpin NIST’s mission and business functions. NIST has a need for GDSFactory Software and maintenance support. The software is an open–source Python library for designing and automating integrated circuits, especially for photonics, quantum, analog, and MEMS devices, enabling users to programmatically create complex layouts, perform Design Rule Checks (DRC), Layout Versus Schematic (LVS), simulate, and generate industry–standard fabrication files like GDSII. It streamlines the chip design workflow from parametric layout generation to simulation and fabrication, making hardware design more accessible, scalable, and efficient. NIST operates clean room facilities in both Gaithersburg and Boulder, each with substantial usage from users across different organizational units. Acquiring GDSFactory+ will bring a standard, well–developed mask–layout tool to all NIST users, improving knowledge sharing and potential collaborations. GDSFactory+ is essential to NIST researchers at both Gaithersburg and Boulder campuses. Lack of this software and support would negatively impact research activities. Line Item 0001: Per–User 2–year License Includes: GDSFactory+ (schematic, layout, and simulation), along with LVS and DRC capabilities; dedicated customer support; Qty: 10; Period of Performance: 6/1/2026–5/31/2028. Interested parties should respond by email, providing company details and capability statements as soon as possible before the deadline.
