Specifying Parameter Distributions in Spectre -- Use Statistics Blocks

Statistics block can contain:

• One or more process blocks;
• One or more mismatch blocks;
• One or more correlation statements;
• A truncate statement (for generating truncated distributions);

Process blocks:

• sampled once per Monte Carlo run

Mismatch blocks:

• sampled once per subcircuit instance

Correlation statements:
Two types of correlation statements that you can use:

• Process parameter correlation statements
• Instance or mismatch correlation statements (matched devices)
