AFFECT(3)

💖 AFFECT(3) — the GENPAT glow-up you didn't know you needed 💖

okay bestie, sit DOWN, because this is AFFECT from the GENPAT functions manual, and it's genuinely iconic. no cap.

---

🌸 NAME 🌸

AFFECT, and the whole GENPAT Package it rolls with. 💅

---

🦋 ORIGIN 🦋

so this software? it belongs to the ALLIANCE CAD SYSTEM, developed by the ASIM team at the LIP6 laboratory of Université Pierre et Marie CURIE, in Paris, France. 🇫🇷✨

like, actual Parisian academic royalty. obsessed.

✨ SYNOPSIS ✨

AFFECT ("pattern_date", "ident", "value");

three little strings and your whole simulation timeline is shook. 🫶

---

🎀 PARAMETERS 🎀

• pattern_date — the date of the pattern, and it can be EITHER an integer (an absolute date) OR + followed by an integer (a relative date — and the reference here is the date of the current pattern, the one last modified using INIT or AFFECT). also important: all the dates are supposed to be expressed in the same time unit, and that unit can only be set once, using SETTUNIT. so choose wisely bestie 😭
• ident — either the name of a bused signal or a scalar. Vectors have to be referenced with their names only, or bit per bit. for example, if b(3 downto 0) exists, you can affect "b", "b(3)" or "b 3". and a path-name must be specified with the syntax:

instance1.instance11.name

• value — the value associated with the signal, and it can be either a based number (ex. binary: 0b011, hexa: 0x3F, octal: 0o56) or a decimal number. the Unknown value (aka any value where a '*' appears) can be used when dealing with an output, a signal, a register, or an input/output when this last one is to be tested. the star ('*') can appear everywhere in a BASED number, but the result will be a "full star" value — for example, "0B0*10" and "0B***" would give the same result. and here's the tea: AFFECT is doing automatically the transformation of the value into a "forced" value or a "tested" value, except for the bidirectional connectors affectation. when a bidirectional is to be tested, you gotta add a '?' character before the value (example : "?0x45f*" instead of "0x45f*"). 🫡

---

💜 DESCRIPTION 💜

"Affect" a value to a signal. that value will be apllied to the signal, at the specified simulation date, and it stays until the end of the simulation or until a new value is affected to the signal. 💫

beware bestie ⚠️ : Inputs have to be affected at the beginning of the simulation (first pattern at 0 ps). By default, signals (except Inputs) are affected with a "full star" value at the first pattern.

and — plot twist — this fonction also sets the current pattern. main character energy fr fr. 👑

---

🌈 EXAMPLES 🌈

okay let's see it in action, this is the part where it eats:

SETTUNIT("ps");
AFFECT ("5", "b", "0B1");
result :            b
<      5 ps> :.....1...;

at simulation date 0 ps the signal b(3 downto 0) receives the value "0001". this value will be kept until the end of the simulation if no more affectation is made. ✨

and now a double feature:

SETTUNIT("ns");
AFFECT ("0", "b", "0B0");
AFFECT ("2", "b", "0B1");
result :            b
<      0 ns> :.....0...;
<      2 ns> :.....1...;

timeline said glow up. 🦋

💀 BUG REPORT 💀

This tool is under development at the ASIM department of the LIP6 laboratory. We need your feedback to improve documentation and tools.

(no seriously, they're literally asking. drop the feedback. 🙈)
