Confusing project budgets

[Ghostbird]

Command

build

Is this a regression?

I don't think so.

Description

When generating a new project, budgets are automatically assigned, however the generated values are really confusing. I accidentally ran into some of these limits. I had to grab a calculator, the build output, make some assumptions, run some calculations, before I could actually understand what these options meant.

It would be nice if these were unambiguous.

The generated project limits rules-as-written are:

• Initial maximum warning: 500 kilobits
• Initial maximum error: 1millibit
• Any component style maximum warning: 2 kilobits
• Any component style maximum error: 6 kilobits

First of all, let's assume that the the m in m should be M, that's a factor 10⁹ difference, but ¹/₁₀₀₀ bits makes no sense here, since we're talking about real storage here. I've only ever used millibits in calculations on pure information.

I analysed this output:

Budget 500.00 kB was not met by 589.00 kB with a total of 1.06 MB

This quickly points in the direction that the b should be a B, it's bytes, not bits. Finally if I run some calculations on this, it clears up another thing (but the output is faulty here too).

(500 + 589)×10³ ≠ 1.06 × 10⁶ (rules-as-written ISO prefixes) (500 + 589)×2¹⁰ ≠ 1.06 × 10³ × 2¹⁰ (floppy disk megabytes) (500 + 589)×2¹⁰ = 1.06 × 10²⁰ (actually intended ISO/IEC 80000-13 binary prefix standard)

From this I can conclude that the numbers used in calculations are actually using the binary measures according to ISO/IEC 80000 (which is the most common for modern systems AFAIK), and the k should be ki and the m should ultimately be Mi.

As you can see, it's no trivial matter to understand what the configuration file actually means with these values.

While not a big priority, it is annoying.
