High level synthesis (HLS) fills the gap between behavioral level and layout level by automatically generating an RTL datapath realization from a behavioral description. The actual circuit layout can be generated later from the RTL datapath using a silicon compiler. A common characteristic of most HLS systems is the lack of consideration to the logic and layout synthesis aspects during the HLS process. The designs generated by these systems may or may not satisfy the initial design requirements and thus the design may need to be changed or modified. One method to address this deficiency is to use estimators, as a bridge between high and low levels, during HLS. The estimators can be iteratively invoked at high levels (e.g. scheduling and allocation) to provide a guiding mechanism to search the design space, which in turn leads to improved design quality and shorter design turnaround time. Motivated by the above observations, in this dissertation we present methods to cover the gap between high and low levels of design hierarchy, including: (1) Scheduling and mixed scheduling-allocation algorithms under time and resource constraints based on Liapunov stability theorem; (2) A neural network based scheduling as an alternative for implementing on parallel machines; (3) A layout estimation method which uses non-probabilistic analytical formulas in a constructive algorithm to estimate the overall area of a datapath; (4) A delay estimation algorithm which identifies false paths at the RTL and computes the static and dynamic critical delay in a datapath. Incorporation of these tools into an experimental HLS system, SYNTEST, has been completed with the overall objective of generating a structural VHDL description of a self-testable RTL datapath from a given behavioral VHDL specification. 1994 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1057603424 http://rave.ohiolink.edu/etdc/view?acc_num=case1057603424 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
