lxStackPartitionParameters

layoutXL lxStackPartitionParameters string "(integer integer)"

Description

Sets the device chaining partition parameters.

The first parameter controls how far up the hierarchy Layout XL looks for opportunities to abut devices. A value of 0 means that chaining can look for abutments only in the same hierarchical level. A value of N means that chaining can look up N levels of hierarchy in order to find abutments. The first parameter can take a value between 0 and 32.

The second parameter sets the maximum number of devices permitted in a chain.

The default is "(0 100)".

The first parameter is always considered by the Generate All From Source and Generate Selected From Source commands. However, the Generate Chained Devices command considers this parameter only if there are 100 instances or more in the selected set.
