Set Ram Initialization
Tools Supported: FastScan
Scope: Setup mode
Usage
SET RAm Initialization Uninitialized | Random
Description
Specifies whether to initialize RAM and ROM gates that do not have initialization
files.
The Set Ram Initialization command allows FastScan to internally generate
random values and place them into all uninitialized RAM and ROM gates. This
command is useful when simulating random patterns.
Arguments
•Uninitialized
A literal that specifies for FastScan to use unknown (X) values to set the
memory elements of all RAM and ROM gates which do not have an
initialization file. This is the default behavior upon invocation of FastScan.
•Random
A literal that specifies for FastScan to use random values to set the memory
elements of all RAM and ROM gates which do not have an initialization file.
Examples
The following example places random values into all uninitialized RAM and
ROM gates:
set ram initialization random
set system mode atpg
set pattern source random
add faults -all
run
