HIGHLAY

highlay - high-light the layout of conductors and/or devices

SYNOPSIS

highlay [-npeoFvmidL -l mask -w width -c outcell] [-N n1,n2... -P p1,p2... -E e1,e2...] cell [namefile]

OPTIONS

	-n		Select nets.
	-p		Select ports.
	-e		Select devices (fets and bipolar transistors).
	-L		High-light with the conductor masks (default: all original masks that are present at that position).

-l mask

Use specified mask for high-lighting (default: all original masks that are present at that position).

-w width

The width of an area with which a selected conductor area should be extended (can only be used in combination with the option -l, default is 0).

-c outcell

Name of output cell (default: HIGH_OUT).

	-o		Do not include the original cell as a sub-cell.
	-F		Include the original cell at the same level.
	-v		Verbose mode. Print the nets, ports and devices that are selected.

The following options are only appropriate when using match results (no namefile is specified).

	-m		Select matching items.
	-i		Select inconclusive items.
	-d		Select deficient items.

-N n1,n2...

Select the nets that are part of groups n1,n2....

-P p1,p2...

Select the ports that are part of groups p1,p2....

-E e1,e2...

Select the devices that are part of groups e1,e2....

DESCRIPTION

Highlay(1ICD) is a program for high-lighting one or more (extracted) conductors and/or devices in a layout-editor/viewer. In order to use highlay for a particular cell, first run the layout-to-circuit extractor space(1ICD) for this cell using the option x. The conductors (nets/ports) and devices that are high-lighted can be specified in two different ways: (1) they are specified in a namefile, or (2) they are selected from the output of the circuit comparison program match(1ICD). When a namefile is specified, the names of the nets, ports and/or devices that are high-lighted are read from this file. The names must be separated by tabs, spaces and/or newline characters. For the devices, the database names must be used. These are the names that are obtained when xsls(1ICD) or xspice(ICD) is used with the option -d, but without the prefix character. Nets, ports and/or devices are selected for high-lighting according to the use of the options -n, -p and/or -e. When no namefile is specified, highlay will read output of the program match for the specified cell. In that case, it will select nets, ports and/or devices according to the use of the options -m, -i, -d, -n, -N, -p, -P, -e and/or -E. A net, port or device is high-lighted if and only if it is selected by one of the options -m, -i or -d and by one of the options -n, -N, -p, -P, -e or -E. In order to obtain correct input for highlay from match, the latter program should be run using the option -edif. Highlay will generate a new cell that contains (default) the high-lighted parts of the specified cell, plus a copy of the specified cell as a sub-cell. The name of the new cell that is generated is (default) HIGH_OUT. This name can be changed by using the option -c. The nets, ports and/or devices that are selected for high-lighting are (default) displayed in their original mask colors. An alternative mask for high-lighting can be specified by using the option -l.

NOTE

Note that names that are printed in spice descriptions as in_1_ in_2_, might be known in the layout database - and must therefore be referred to in the namefile of highlay - as in[1] in[2].

EXAMPLE

An example of a namefile "latch.hil" for highlay is as follows: vdd a1 a2 _T2 This namefile may be used to obtain a cell HIGH_OUT in which the nets vdd, a1 and a2 and the device _T1 of cell latch are high-lighted, as follows. $ highlay -n -e latch latch.hil
