The throughput and processing requirements of the CMS L1 Trigger for HL-LHC require platforms with high-end FPGAs and many high speed optical links. The Ocean platform features the largest ZYNQ Ultrascale+ SoC and 72 transceivers connected to on-board optics reaching rates up to 28 Gbps. The Octopus^2 design targeted for the CMS Muon Trigger at HL-LHC features a Virtex Ultrascale+ 13P FPGA in and 128 bi-directional links connected through copper to QSFP and QSFP-DD optics. Signal integrity results, comparison of different layout strategies and heat management for large FPGAs featuring lidless packages will be discussed..
