Q

What checks/settings on a check are recommended for a first time user for a test run ? Selecting certain checks / settings gives me too many errors.

A

Some checks are very netlist and use specific . Running these on a netlist/project for which it is not appropriate will lead to too many errors .Others are typical to almost any netlist.

Insight checks include

• Power Connections
• Floating Gates
• Load-Drive (Fanout , Keepers , Victim aggressor etc.)
• ESD

We can divide checks/settings into 2 categories :

• Recommended - Commonly used settings/check.
• Custom - Netlist and Use specific.

Below is a classification of the checks in order of :Appropriate to all Netlists-> Netlist /use specific

Power Connections

• Recommended
  • Mosfet Gate (over-voltage)
  • Mosfet Drain/Source (over-voltage)
  • Mosfet Leaking (Appropriate-Use)
  • Mosfet Gate-Overdriven (Appropriate-Use)
  • Diodes, Capacitors , Resistors over-voltage
• Custom
  • Name-based checking / crossing one domain name to another.
  • Substrate Invalid voltage.
  • Substrate : Foreign rail, SoftTie.

Floating Gates

• Recommended Settings
  • Effort slider at 2
  • Report Everything: No
  • Check Top Level : No
  • Find cutoff Paths : Yes
  • Find unsafe power crossings :No
• Custom/High-effort Setting
  • Effort slider at 4
  • Report Everything:Yes
  • Check Top Level : Yes
  • Find cutoff Paths : Yes
  • Find unsafe power crossings :Yes

ESD

ESD is meant for full customization based on user specific ESD-rule book - No recommendation

Load/Drive

Load/Drive is very specific and non-customizable check - No recommendation
