- It's located at: It's found in the Services tab under: USB Flash Driver Format Tool (Ufix-II). It wasn't easy getting PNY to release the tool from in-house. I had to swear at a few people. They had a 32GB tool that could fix it but it would break the capacity on 64GB models. There are also other available recovery/LLF tools on their site.

Description¶
The
UFix
and SFix
types correspond to a vector of bits that can be used for fixed-point arithmetic.Declaration¶
The syntax to declare a fixed-point number is as follows:
Unsigned Fixed-Point¶
Syntax | bit width | resolution | max | min |
---|---|---|---|---|
UFix(peak: ExpNumber, resolution: ExpNumber) | peak-resolution | 2^resolution | 2^peak-2^resolution | 0 |
UFix(peak: ExpNumber, width: BitCount) | width | 2^(peak-width) | 2^peak-2^(peak-width) | 0 |
Signed Fixed-Point¶
Syntax | bit width | resolution | max | min |
---|---|---|---|---|
SFix(peak: ExpNumber, resolution: ExpNumber) | peak-resolution+1 | 2^resolution | 2^peak-2^resolution | -(2^peak) |
SFix(peak: ExpNumber, width: BitCount) | width | 2^(peak-width-1) | 2^peak-2^(peak-width-1) | -(2^peak) |
Format¶
The chosen format follows the usual way of defining fixed-point number format using Q notation. More information can be found on the Wikipedia page about the Q number format.
For example Q8.2 will mean a fixed-point number of 8+2 bits, where 8 bits are used for the natural part and 2 bits for the fractional part.If the fixed-point number is signed, one more bit is used for the sign.
The resolution is defined as being the smallest power of two that can be represented in this number.
Note
To make representing power-of-two numbers less error prone, there is a numeric type in
spinal.core
called ExpNumber
, which is used for the fixed-point type constructors.A convenience wrapper exists for this type, in the form of the exp
function (used in the code samples on this page).Examples¶
Assignments¶
Valid Assignments¶
An assignment to a fixed-point value is valid when there is no bit loss. Any bit loss will result in an error.
If the source fixed-point value is too big, the
.truncated
function will allow you to resize the source number to match the destination size.Example¶
From a Scala constant¶
Scala
BigInt
or Double
types can be used as constants when assigning to UFix
or SFix
signals.Example¶
Raw value¶
The integer representation of the fixed-point number can be read or written by using the
raw
property.Example¶

The following operators are available for the
UFix
