insystem_memory_edit

write_content_to_memory

Usage

write_content_to_memory -content <content string> [-content_in_hex] -instance_index

<instance index> -start_address <starting address> -word_count <word count>

Options

-content <content string>: A string that represents all word values concatenated

together in order in either binary or hexadecimal format

-content_in_hex: The memory content string is represented in hexadecimal format

-instance_index <instance index>: Index of the editable memory instance to modify

-start_address <starting address>: The lowest memory address to be modified

-word_count <word count>: The number of contiguous memory words to be modified

Description

Writes the data represented in the bit stream into the specified editable memory instance starting from the

specified address.

The bit stream should be ordered by word from high address to low address, contiguously without gaps or

delimiters. If the starting address is ADDR, and word count is N, the order is <word @ ADDR + N - 1> ...

<word @ ADDR + 1><word @ ADDR> In each word, the MSB is on the left, LSB is on the right. The bit

stream can be in either binary or hexadecimal. For example, if the word width is 8, and two words, 1 and

128, are written to address 0 and 1 respectively, the bitstream should be "1000000000000001" in binary or

"8001" in hexadecimal. The TCL command is write_content_to_memory -instance_index 0 -start_address 0

-word_count 2 -content "1000000000000001" or write_content_to_memory -instance_index 0 -start_address

0 -word_count 2 -content "8001" -content_in_hex

Example

# Instance 0 is configured as {0 1024 8 RW ROM/RAM mem0}

# Initiate a editing sequence

begin_memory_edit -hardware_name "USB-Blaster \[USB-0\]" -device_name \

"@1: EP1S25/_HARDCOPY_FPGA_PROTOTYPE (0x020030DD)"

# Write memory content using binary string

write_content_to_memory -instance_index 0 -start_address 575 -word_count \

2 -content "0000001011011100"

# Read back memory content in binary string written

puts \

[read_content_from_memory -instance_index 0 -start_address 575 \

-word_count 2 ]

# Write memory content using hexadecimal string

write_content_to_memory -instance_index 0 -start_address 575 -word_count \

2 -content "E2F1" -content_in_hex

# Read back memory content in hexadecimal string written

puts \

[read_content_from_memory -instance_index 0 -start_address 575 \

-word_count 2 -content_in_hex]

# End the editing sequence

end_memory_edit
