architectures, packages, package bodies, and conﬁgurations) and other derived data in

libraries that are organized within a Library.Cell:View (L.C:V) structure.

Three conﬁguration ﬁles help you manage your data and control the operation of the various

tools and utilities:

■ cds.lib

Deﬁnes your design libraries and associates logical library names with physical library

locations.

■ hdl.var

Deﬁnes variables that affect the behavior of tools and utilities.

■ setup.loc

Speciﬁes the search order that tools and utilities use when searching for the cds.lib

and hdl.var ﬁles.

See the chapter on setting up your environment in the

Affirma NC VHDL Simulator Help

for detailed information about these conﬁguration ﬁles.

Selection

NCLaunch presents two different browsers that display data about your ﬁles and designs.

Both browsers are simply displaying the information that is stored in your directories in a way

that makes the information easier to interact with.

The ﬁles that make up your design are presented in the

File Browser. The elements that are

stored within your library are presented in the

Library Browser. You can select and manipulate

any objects displayed within these browsers that can be used as input to NC based tools, or

that were generated as output from such tools.

Within the File Browser, a Verilog ﬁle (usually represented by using the .v ﬁle extension) and

a VHDL ﬁle (usually represented by using the .vhd ﬁle extension) are objects that you can

use with the appropriate NC compiler. When you select a ﬁle with a known extension, the

icons that represent these tools become enabled and you can simply press the button on the

tool bar to run the appropriate compiler.

For each NC tool that is enabled on the tool bar, there is at least one selectable object

displayed in one of the browsers on which you can use the tool. Thus, you can step through

simulation by selecting the appropriate input to the tool that you wish to run. By enabling and

disabling the tool bar icons, you will quickly become aware of the required input for each tool.

Customization of File Types and Available Commands

NCLaunch provides you with two ways to customize your default operations and bind them to

speciﬁc ﬁle types.

■ You can change the extension(s) that is associated with an existing operation by using

the

Edit - Setup File Types

menu option. For example, if you use the extension .vh

instead of .vhd to represent a VHDL ﬁle, you can use the

Edit - Setup File Types

option to change this mapping.

■ You can deﬁne a new operation and then associate it with an extension and ﬁle type. For

example, you can easily set up the system to run make if you double-click on a Makeﬁle.

By default, NCLaunch has a predeﬁned set of operations for each NC tool, based on the

expected input for that tool. These default operations are itemized in

Figure 2-11 on page 29.)

For the set of known tools, you can submit a selected ﬁle with the correct ﬁle extension to the

tool along with its predeﬁned set of options simply by pressing the appropriate tool bar button.

In this case, the command line that you submit is:

If you change a ﬁle extension, the behavior of the tool remains the same when you submit the

run. If you deﬁne a new command that is not one of the predeﬁned set of tools, NCLaunch

submits the command exactly as speciﬁed. You must specify the exact syntax and also

specify whether the new command allows multiple selections, and whether it operates on a

ﬁle or a directory.

For example, if you want to add a customized operation for Makeﬁles, you can specify make

-f %f where %f speciﬁes the location of the selected ﬁle. Or you can state that you simply

want to run make by specifying: "make" without the %f.

Tools and Options

NCLaunch provides a set of predeﬁned options for each of the available NC tools. These tools

include ncvlog, ncvhdl, ncelab and ncsim. You can change the default options to each

tool by selectin it from the

Tools - Advanced Options...

pulldown on the main menu. When

you change the options to a tool, those options remain in effect until you change them again.

You can specify only one set of options per tool. These options apply to any invocation of the

tool, whether you invoke it from the pulldown menu, the tool bar, or a popup menu.

A small set of options is available only on each tool invocation form. These options are the

ones that tend to change most frequently, such as method of invocation (batch, interactive or

graphical), log ﬁlename, and work library. Once you set these options on a tool invokation

form, the options remain in effect until you change them.
