High Multi-Speed Time-Triggered Ethernet

LeWiz Phase 1 researchnbsp;showed strong needs for US based time-triggered Ethernet (TTE) solutions for use by USnbsp;agencies and their contractors. TTE is an SAE AS6802 standard for aerospace applications. Current market leader is an Austrian company. NASA used 1Gbps foreign solution in Artemis projects and called for TTEnbsp;development by US companies in its 2022 SBIR Z2.02 topic. The US Navy also has requested for US basednbsp;TTE solution. In NASA Phase 1, we developed a TTEnbsp;IP core - scalablenbsp;to speednbsp;up to 100Gbps. We also developed a working relationship with NASA to do joint testing for potential use in the Artemis program. nbsp;LeWiz also worked with the US Navy to develop low-end IP core to target endpoint ASIC devicesnbsp;ndash; specifically for slower sensors and othernbsp;end systems. In NASAnbsp;Phase 2, we propose to further develop the hardware and software to target high performance TTE switching systems suitable for backbone network and others. LeWizrsquo;s works with NASA and the Navy will produce a comprehensive solution for both endpoint and switching applications. By working with actual end-user experts from Artemis Program, LeWiz products will meet requirements for space travel including radiation hardened and fault tolerant capabilities - more suitable for commercialization to the Navy and others fornbsp;hypersonic and aerospace applications. Proposed Phase 2 TTE switch would support 1G to 10Gbps, scalable in port count with speed up to 100Gbps - allowing us to quickly create a family of products to meet different customer requirements. Products achieved extremely high accuracy timing rate, designed for low-latency, supportnbsp;priority-based, mixed traffic: PCF, TT, RC, BE; Arinc664p7 compatible, interface to copper or fiber, support high end/rugged OpenVPX or low-end/low-cost form factors.nbsp;In addition, Phase 2 will also develop application software and easy to use tool for designing TT network. Also validate them with the developed hardware. nbsp;
