Abstract
A congestive placement preventing apparatus applied to a circuit layout including electrical devices is provided. The congestive placement preventing apparatus includes an analyzing module, a reserving module and a placing module. The analyzing module performs a routing congestion analysis on the circuit layout to generate an analysis result of the circuit layout. The reserving module correspondingly disposes a plurality of blockages in the circuit layout according to the analysis result, so that a first space with the blockages and a second space are formed in the circuit layout. After the placing module places the electrical devices in the second space, the placing module removes the blockages from the first space, and redistributes the electrical devices in the first space and the second space according to a redistribution rule.
