genhdltdb

Generate timing databases for specified target device, device speed grade, and synthesis tool

Since R2021a

Syntax

genhdltdb('Name','Value')

Description

genhdltdb('Name','Value') generates timing databases for the target device with options specified by using name-value arguments. You can specify the device family name, the device name, the device package, and the device speed grade. This function exports the generated timing database MAT-files to the specified timing database path.

To generate timing databases, the function characterizes basic design components (such as Simulink^® blocks, block architectures, and subcomponents of those blocks) for the specified target device. HDL Coder™ analyzes these timing databases to estimate the critical path in your design. For more information, see Critical Path Estimation Without Running Synthesis.

Note

This function generates timing databases for Xilinx^® devices only, not Intel^® and Microchip devices.

Generate Timing Data for Xilinx Artix-7 Target Device

Generate timing databases for the Xilinx Artix^®-7 target device. Export generated timing database MAT-files to the C:\Work\Database folder. Set the synthesis tool path to 'C:\Xilinx\Vivado\2019.2\bin\vivado.bat'.

To generate timing database for the target device, specify target device configuration parameters, such as device family, device name, device package, and device speed grade, in a single argument 'SynthesisDeviceConfiguration'.

genhdltdb('SynthesisDeviceConfiguration',{'Artix7','xa7a100t','csg324','-1I'}, ...
    'TimingDatabaseDirectory','C:\Work\Database', ...
    'SynthesisToolName','Xilinx Vivado', ...
    'SynthesisToolPath','C:\Xilinx\Vivado\2019.2\bin\vivado.bat');

Alternatively, specify target device configuration parameter in separate arguments.

genhdltdb('SynthesisDeviceFamily','Artix7', ...
   'SynthesisDeviceName','xa7a100t', ...
   'SynthesisDevicePackage','csg324', ...
   'SynthesisDeviceSpeedGrade','-1I', ...
   'TimingDatabaseDirectory','C:\Work\Database', ...
   'SynthesisToolName','Xilinx Vivado', ...
   'SynthesisToolPath','C:\Xilinx\Vivado\2019.2\bin\vivado.bat');

Note

When you use the genhdltdb function to generate a timing database for a specific device, the function can run for a long time until the database is created.

Generate Timing Data for Xilinx Kintex UltraScale+ Target Device

Generate timing databases for the Xilinx Kintex^® UltraScale+™ target device. The target device is xcku11p-CIV-ffva1156-1-e. Enter the device name without 'CIV', as it is not required for setting the part number. Export generated timing database MAT-files to the C:\Work\Database folder. Set the synthesis tool path to 'C:\Xilinx\Vivado\2019.2\bin\vivado.bat'.

To generate timing database for the target device, specify target device configuration parameters, such as device family and device name, in a single argument 'SynthesisDeviceConfiguration'. In this target device, the device package and speed grade is included in the device name.

genhdltdb( 'SynthesisDeviceConfiguration',{'Kintex Ultrascale+', ...
    'xcku11p-ffva1156-1-e'}, ...
    'TimingDatabaseDirectory','C:\Work\Database', ...
    'SynthesisToolName','Xilinx Vivado', ...
    'SynthesisToolPath','C:\Xilinx\Vivado\2019.2\bin\vivado.bat');

Alternatively, specify target device configuration parameters in separate arguments.

genhdltdb('SynthesisDeviceFamily','Kintex Ultrascale+', ...
    'SynthesisDeviceName','xcku11p-ffva1156-1-e', ...
    'TimingDatabaseDirectory','C:\Work\Database', ...
    'SynthesisToolName','Xilinx Vivado', ...
    'SynthesisToolPath','C:\Xilinx\Vivado\2019.2\bin\vivado.bat');

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: 'SynthesisToolPath','C:\Xilinx\Vivado\2019.2\bin\vivado.bat' sets the synthesis tool path to C:\Xilinx\Vivado\2019.2\bin\vivado.bat.
