This extension provides robust syntax highlighting and code snippets for HSPICE netlists (.sp, .lis, .hsp). It is designed to make circuit simulation workflows faster and less error-prone by providing "cheat sheet" style auto-completion.
Features
Syntax Highlighting:
Case-insensitive support (e.g., .TRAN and .tran are both recognized).
Differentiates between Simulations (.tran, .ac), Definitions (.subckt, .param), and Options (.option).
Highlights engineering units (u, n, meg, k).
Supports full-line comments (*) and inline comments ($).
Intelligent Snippets:
Auto-completion for complex sources (PULSE, SIN, PWL).
Templates for analyses (.tran, .dc, .ac) with tab-stops.
Dropdown menus for .meas analysis types.
