Timing-Driven Nonuniform Depopulation-Based Clustering

Figure 3

Impact of unrelated block clustering, Net 1 followed by Net 2. (a) introduces an inter-CLB delay and an external connection between CLB1 and CLB2. (b) no inter-CLB delay, no external connection, and less routing resource demand when CLB1 is under-utilized.
