4GL Access: RW

The UpdateBias attribute specifies a field's bias setting when the CurMode attribute for the frame is set to FM_UPDATE.

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 CurBias Attribute.

OpenROAD enforces this setting whenever the CurMode setting of the frame is FM_UPDATE. If you set this attribute at a time when the CurMode is something other than FM_UPDATE, it is not enforced until the CurMode setting is changed to FM_UPDATE. If you set the CurBias attribute when the CurMode is FM_UPDATE, this attribute is changed.
