Cad Tools For Synthesis Of Sleep Convention Logic, Parviz Palangpour
Cad Tools For Synthesis Of Sleep Convention Logic, Parviz Palangpour
Graduate Theses and Dissertations
This dissertation proposes an automated flow for the Sleep Convention Logic (SCL) asynchronous design style. The proposed flow synthesizes synchronous RTL into an SCL netlist. The flow utilizes commercial design tools, while supplementing missing functionality using custom tools. A method for determining the performance bottleneck in an SCL design is proposed. A constraint-driven method to increase the performance of linear SCL pipelines is proposed. Several enhancements to SCL are proposed, including techniques to reduce the number of registers and total sleep capacitance in an SCL design.
Silicon Germanium Sram And Rom Designs For Wide Temperature Range Space Applications, Matthew Barlow
Silicon Germanium Sram And Rom Designs For Wide Temperature Range Space Applications, Matthew Barlow
Graduate Theses and Dissertations
This thesis presents a design flow from specifications and feature requirements to embeddable blocks of SRAM and ROM designs from 64 bytes to 1 kilobyte that are suitable for lunar environments. The design uses the IBM SiGe 5AM BiCMOS 0.5 micron process for a synchronous memory system capable of operating at a clock frequency of 25 MHz. Radiation mitigation techniques are discussed and implemented to harden the design against total ionizing dose (TID), single-event upset (SEU), and single-event latch-up (SEL). The memory arrays are also designed to operate over the wide temperature range of -180 °C to 125 °C. Design, …
