o Write Line Stuck-Off Faults on Multi-Write Port RAMs:
Vector 1 - For the first data line of the first non-fault write port, write 0
into address 0.
Vector 2 - For the first data line of the fault write port, write 1 into
address 0.
Vector 3 - From the first data line of the first read port, read 1 from
address 0.
o Write Line Stuck-On Faults:
Vector 1 - For the first data line of the fault write port, write 1 into
address 0.
Vector 2 - For the first data line of the fault write port, write 0 into
address 0.
Vector 3 - From the first data line of the first read port, read 0 from
address 0 with the first data line of the fault write port at 1.
Arguments
• Combinational
A literal specifying that the test patterns contain combinational RAM patterns.
This is the default behavior upon invocation of FastScan.
• Ram_sequential
A literal specifying that the test patterns contain sequential RAM test patterns.
• -Random
An optional switch that forces patterns created by the random pattern source to
be RAM_sequential.
• -Depth number
An optional switch and integer pair that specifies the depth of non-scan
sequential elements in the design. The integer must be a value between 0 and
255. The default sequential depth upon invocation of FastScan is 0.
