tech file to correct the underlying problem with the SkyWater sky130 process in which a different layer/purpose pair is used for TEXTTYPE and DATATYPE for the same layer. Previously, all output from magic writes the same pair for both when writing a port label. The new method preserves existing syntax, although there are some differences based on what order the "port" statement appears relative to other types for the same layer.

<H3>Summary:</H3>
|
|
<BLOCKQUOTE>
|
|
The <B>writeall</B> command generates a popup dialog prompting
|
|
for action on writing each cell definition in the layout
|
|
hierarchy to disk. As shown in the figure below, the popup
|
|
dialog presents five choices:
|
|
<DL>
|
|
<DT> <B>write</B>
|
|
<DD> Writes the single cell and continues the prompting for
|
|
the next cell.
|
|
<DT> <B>flush</B>
|
|
<DD> Reverts the cell to what was originally on the disk, like
|
|
the <B>flush</B> command. Continues prompting for the
|
|
next cell.
|
|
<DT> <B>skip</B>
|
|
<DD> No action for the indicated cell definition; continue
|
|
prompting for the next cell.
|
|
<DT> <B>abort</B>
|
|
<DD> Stop all writing and terminate the command with no further
|
|
prompting or processing.
|
|
<DT> <B>autowrite</B>
|
|
<DD> Write all the cells, with no further prompting.

|
With the option <B>writeall force</B>, the command writes all cells
|
|
in the hierarchy with no prompting. If one or more cell names
|
|
follows <B>write force</B>, the cells listed will be written
|
|
(action "write") and all other cells will be ignored (action
|
|
"skip"). <P>
|
|
|
|
With the option <B>writeall modified</B>, the command writes all
|
|
cells in the hierarchy which have been modified, ignoring those
|
|
cells marked as needing only a bounding box or timestamp update. <P>
|
|
|
|
With the option <B>writeall noupdate</B>, the command writes all
|
|
cells in the hierarchy like it would for <B>write force</B>, but
|
|
it does not update timestamps. <P>
