Vertical search paths

@application vertical_pin

@application vertical_pcb

@application vertical_hdl

@text

As of version 15.5a, Vertical can now use search paths when opening scripts or database

files for reading. All file writes are in the current directory.

@break

For the PC the search path is :

@listing

.;c:/cygwin/usr/local/vert_files

@text

Or in english : look in the current directory '.' and then look in

'c:/cygwin/usr/local/vert_files'.

@break

For PC; filenames containing ':' or starting with either '/' or '.' are not searched down the

path,

@break

The path is in the environment variable called 'VERTICAL_PATH', which can either be

set in the shell (MSDOS or cygwin) which invokes vertical, or as a command from within

a Vertical script. e.g.

@listing

setenv VERTICAL_PATH "$(VERTICAL_PATH);/home/project/reference_data"

@text

This will make Vertical search in the usual places and then in the additional directory.

@break

For the HPUX port of Vertical the search path is

.;.caddata/vert_files

@text

For HPUX; filenames starting in '/' and '.' are not searched for down the path. These two

characters are normally used to specify a definite path, either relative to the current working

directory or absolute relative to the file system root.

Vertical script command notation: Command line and script files

@application vertical_pin

@application vertical_pcb

@application vertical_hdl

@text

Vertical uses its own 'shell' like command language. In this language, quoting a string

simply means that spaces appearing inside strings can be passed into Vertical as a single

argument. Normally spaces are used to delimit parameters in a command.

@break

When the command is listed out the following notation is used.

@text

If an item is given without angle ( '<' '>' ) brackets then the word is typed as is. e.g.

@listing

command

@break

If '<' '>' angle brackets are given then this an item such as a filename which is user defined.

e.g. Command followed

@listing

command <filename>

@break

If followed by an asterisk '*' it means in this context that more than one of these items

may be entered. It is not the same as a regular expression used within one of these items. e.g.

command followed by several items

@listing

command <item> *

@break

If '[' ']' square brackets are given then the item is optional. e.g. command with an optional

parameter

@listing

command [ <optional> ]

@text

More than one of these may appear at a time on the same item. e.g. Optional list of letters.

@end

@title

Vertical database file notation: Database files

@application vertical_pin

@application vertical_hdl

@application vertical_pcb

@text

Vertical handles several different database file formats. These are :

@listing

Altera .acf      : tagged as AHDL

Verilog          : tagged as VERILOG

VHDL             : tagged as VHDL

Vertical Native  : initial state and outside other tagged blocks

@text

They are all read in by a single database handler which can switch between different

languages on the fly.

@break

In all cases the Vertical parser begins expecting Vertical Native file format, and then

it is switched into other modes by the presence of tag  keywords

@break

These bracket the code. e.g.

@listing

VHDL -- this indicates following syntax.

  entity nine is

    (

    );

  end entity nine;

  architecture seven of nine is

-- vertical read_off

 this code will not be seen by vertical, as it has

 tags in the comments.

 DONT start comments with the word 'VERTICAL' as it is seen an

 an escape into vertical database language.

-- vertical read_on

  begin

  end;

END; -- this belongs to Vertical

@text

Because Vertical recognises the comments that are found in

all of the HDL's that it understands, it is possible to feed

a native HDL file in with Vertical tags in comments.

e.g.

@end

@title

regular expression: Information on wildcards in Vertical

@application vertical_pin

@application vertical_hdl

@application vertical_pcb

@text

The wildcards now used in several commands conform to standard regular expressions.

If no 'special' characters are given then patterns must match exactly, except that

the case of alphabetic characters is ignored.

@break

For instance: to select :

@listing

pattern   meaning

-------   -------

X2[1-7]   'X' or 'x', '2' and then digit '1' to '7'

.*        any char zero or more times (anything)

X[0-9]+   'X' or 'x', followed by one or more digits

(expr)    A pattern to be matched that can be used in a string replace.

          Each bracketed expression can be used in a replacement string

          &1 is the first pattern. &0 is the whole of the matched string.

@text

On cygwin and Unix 'man regex' will work to tell you more.

@break

The edit_pin ident command and edit_pin type

command documentation has more on regular expressions.

@break

Use '\' characters to escape special characters.

/******************** Read a data file ***********************/

/*

@title

read <filename> [<identifier_suffix> | "" ] [ <arg>* ]

@application vertical_pcb

@application vertical_pin

@application vertical_hdl

@text

Read a data file in to the internal database. If <suffix> is

given, the newly read socket and net identifiers are suffixed

with the suffix given. This is the means by which a single PCB

netlist file is given a unique identity. In this way the same

netlist may be repeated many times, but every object is given

an unique identifier.

In other words if the netlist is read in twice, once with the

suffix 'a' and once with the suffix 'b' then a socket 'U1' in

the netlist will become two sockets : 'U1a' and U1b' in the

combined netlist.

@break

String concatenation WARNING:

@break

If you have a set of sockets in the PCB netlist file  with

identifiers U1 to U 20 and you decide to suffix a new ACF file

being read with "0" then U1 in the new file will match U10 in

the old file and will 'vanish' or be confused with U10 in the

old file. The best way to avoid this problem is to

It is normal to use an underscore character as in "_" to

prefix the suffix to avoid this.

@break

In addition any arguments after the suffix field (which can be omitted if a "" null string is

given) can be used as macro variables $0, $1 and so on inside the database file.

e.g.

@listing

read conn.txt ""  x1_a x1_b

@text

Will, if the file conn.txt contains the following

@listing
