Knowledge Check

What is the MHS file?

What does the PlatGen tool do?

What tool is used to place executable code in an FPGA block

RAM?

25- 2 Course Review


2/12


Answers

What is the MHS file? The MHS file is the Microprocessor Hardware Specification; it specifies

processors, hardware peripherals, bus connections, and address spaces for

the hardware

What does the PlatGen tool do? PlatGen takes the MHS file and creates the system and peripheral netlists,

HDL wrapper files, BMM file, etc.

What tool is used to place executable code in an FPGA blockRAM?

The BitInit tool will take the BMM file and create the proper initialization forthe block RAM that is assigned to the executable memory space

How can you add or change hardware configuration settings oncethe hardware system is build?

What does the LibGen tool do?

What is the difference between system.bit and download.bit files?

25- 4 Course Review


3/12


Answers

How can you add or change hardware configuration settings oncethe hardware system is build? Select an IP instance in the System Assembly View panel, right click on it,

and select Configure IP

Select available tabs and appropriate options and make changes to theparameters

Alternately, you can modify MHS f ile with correct Parameter name andvalue

What does the LibGen tool do? Read MSS file and generate libraries

What is the difference between system.bit and download.bit files? The system.bit file contains only hardware description whereas

download.bit file contains both hardware description as well as executablesoftware
