The coder generates scripts as part of the code and test bench generation process. Script files are generated in the target folder.
When HDL code is generated for a filter,
coder writes the following script files:
ModelSim® compilation script. This script contains commands to compile
the generated filter code, but not to simulate it.
When test bench code is generated for a filter
the coder writes the following script files:
ModelSim compilation script. This script contains commands to compile
the generated filter and test bench code.
ModelSim simulation script. This script contains commands to run a
simulation of the generated filter and test bench code.
You can enable or disable script generation and customize the names and content of generated script files by:
Setting the corresponding options in the Generate HDL dialog box. Select the EDA Tool Scripts tab, and click Compilation script or Simulation script from the menu in the left column. See Customize Scripts for Compilation and Simulation.
A generated EDA script consists of three sections, which are generated and executed in the following order:
An initialization (
Init) phase. The
Init phase performs required setup actions, such
as creating a design library or a project file.
A command-per-file phase (
Cmd). This phase of the
script is called iteratively, once per generated HDL file.
A termination phase (
Term). This phase is the
final execution phase of the script. One application of this phase is to
execute a simulation of HDL code that was compiled in the
The coder generates scripts by passing format character vectors to the
fprintf function. Using the UI options (or
generatehdl properties) summarized in the following
sections, you can pass in customized format character vectors to the script
generator. Some of these format character vectors take arguments, such as the
top-level entity or module name.
You can use valid
fprintf formatting characters. For
'\n' inserts a newline into the script file.
To view and set options in the EDA Tool Scripts dialog box:
Open the Generate HDL dialog box.
Click the EDA Tool Scripts tab.
The Compilation script options group is selected, as shown.
The Generate EDA scripts option controls the generation of script files. By default, this option is selected, as shown in the preceding image.
If you want to disable script generation, clear this check box.
The list on the left of the dialog box lets you select from several categories. Select a category and set the options as desired. The categories are:
Compilation script: customize scripts for compilation of generated VHDL or Verilog code. See Compilation Script Options.
Simulation script: customize scripts for HDL simulators. See Simulation Script Options .
Synthesis script: customizing scripts for synthesis tools. See Automation Scripts for Third-Party Synthesis Tools .
The custom character vectors for each section are passed to
fprintf to write each section of the selected
script. You can use format character vectors supported by the
fprintf function. Some of the character vectors
include implicit arguments.
|Compile initialization||Library name|
|Compile command for VHDL and Compile command for Verilog||
|Compile termination||No implicit argument|
|Compile initialization||No implicit argument|
|Simulation termination||No implicit argument|
The figure shows the Compilation script pane, with the options set to their default values.
The coder generates a script called
vlib work vcom firfilt_copy.vhd
vlib work vcom firfilt_copy.vhd vcom firfilt_copy_tb.vhd
Setting Simulator Flags for Compilation Scripts. You have the option of inserting simulator flags into your generated compilation scripts. This option is included in the compilation scripts for both the standalone filter and the test bench. For example, you can specify a compiler version. To specify the flags:
Click Test Bench in the Generate HDL dialog box.
Type the flags of interest in the Simulator
flags field. In the figure, the dialog box specifies
ModelSim simulator use the
option for compilation.
The coder generates a simulation script when you generate a test bench. The figure shows the Simulation script pane, with the options set to their default values.
The coder generates a script called
