User1Bias Attribute
Data Type: smallint
4GL Access: RW
The User1Bias attribute specifies a field's bias setting when the CurMode attribute for the frame is set to FM_USER1.
The valid settings are the same as for CurBias Attribute.
If the field is a composite field, setting this attribute affects the children as well. For more information about the relationship between parent and child biases, see the description of the CurBias Attribute.
OpenROAD enforces this setting whenever the CurMode setting of the frame is FM_USER1. If you set this attribute at a time when the CurMode is something other than FM_USER1, it is not enforced until the CurMode setting is changed to FM_USER1. If you set the CurBias attribute when the CurMode is FM_USER1, this attribute is changed.
In this mode, most fields default to FB_CHANGEABLE. Shape and trim fields default to FB_VISIBLE.
