mixed-signal-cosim SKILL.md skillA
mixed-signal-cosim from vibeic/vibe-ic is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vibeic/vibe-ic/mixed-signal-cosim@git:20260613.86cacb4Pins git:20260613.86cacb4 in mdr.lock. Pin the fingerprint instead.

Run mixed-signal co-simulation — digital gate-level Verilog + analog behavioral models together. Use when the user says "mixed-signal sim", "co-simulation", "digital-analog integration test", or at Step A9 of the analog track.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Mixed-Signal Co-Sim
Verifies that analog blocks work correctly when connected to the digital logic by running a combined simulation: digital gate-level netlist + analog behavioral Verilog models (derived from SPICE corner results).
## When to use
- Step A9 of the analog track (final integration verification)
- After `analog-hardmacro-gen` has produced behavioral Verilog models
- When the user says "does the digital logic talk correctly to the LDO?"
## Inputs
1. Digital gate-level netlist (`synth/netlist.v` or `pnr/routed.v`)
2. `hardmacro/<block>/<block>.v` — behavioral Verilog per analog block
3. Digital testbench (`sim/tb_*.v`)
4. `analog/<block>/spec.json` — expected analog behavior
## Approaches (in order of preference)
### Approach 1: Behavioral Verilog (default, works with iverilog)
Generate enhanced behavioral models that go beyond `assign vout = en ? 1'b1 : 1'bz`:
```verilog
module ldo_1v8 (input vin, input en, input [2:0] trim, output reg vout_ok);
// Model startup delay from SPICE measurements
parameter STARTUP_DELAY_NS = 50; // from corner_results.json
initial vout_ok = 0;
always @(posedge en) begin
#STARTUP_DELAY_NS vout_ok = 1;
end

How to install
mdr add vibeic/vibe-ic/mixed-signal-cosim@sha256:0a3fa4982098b5a9The line at the top of this page pins the label git:20260613.86cacb4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
