It is an important stage in the very large-scale integration (VLSI) design flow, because it affects routability, performance, heat distribution, and to a less extent, power consumption of a design. Traditionally, it is applied after the logic synthesis stage and before the routing stage. The ...

The HSA method hierarchically divides a given problem into some sub-problems applying the SA method at each stage and makes it possible automatically to choose suitable parameters in the cost functions at each stage of the hierarchical computation. Theoretical consideration and application of the HSA ...

Yifan Chen developed the 2-stage flow and improved the optimizer for macro placement in DREAMPlace 4.1. Set use_bb to 1 to turn on BB-step and macro_place_flag to 1 to enable 2-stage flow for macro placement. Yiting Liu contributed the GiFt operator for placement initialization, published ...

Macros (Halo) blockage :usually placed around Macros so that no other macro sit adjacent to that (To save routing congestion at later stage) In case of Routing Blockage,you have to define Layer Number which you want to block. I means to say, there is a area X and In that area you ...
Condition (2) may not be mandatory. This depends on the level of hierarchy. It is clearly mandatory at the very first cut. On lower levels of hierarchy, however, one may allow condition (2) to be slightly violated. This may lead to overflow during an intermediate wiring stage, but finall...
