ASIC Physical Layout for the HCD ASIC

An integrated circuit (IC) physical layout has been developed for the HCD ASIC - an application-specific integrated circuit that decodes digital command signals transmitted from a ground station to a spacecraft (uplink commands). The HCD ASIC is described in "Hardware-Command-Decoding ASIC" (NPO-19615), which appears elsewhere in this issue of NASA Tech Briefs. The present physical layout will be converted to a mask for IC fabrication of the HCD ASIC.
