A Negative Reinforcement Method for PGA Routing
We present an efficient and effective method for the detailed routing of symmetrical or sea-of-gates FPGA architectures. Instead of breaking the problem into 2-terminal net collec...

On Area/Depth Trade-off in LUT-Based FPGA Technology Mapping
In this paper we study the area and depth trade-off in LUT based FPGA technology mapping. Starting from a depth-optimal mapping solution, we perform a number of depth relaxation o...

Rotation Scheduling: A Loop Pipelining Algorithm
— We consider the resource-constrained scheduling of loops with interiteration dependencies. A loop is modeled as a data flow graph (DFG), where edges are labeled with the numbe...
