SystemVerilog enhances the concatenation operation to allow concatenation of variables of type string. In general, if any of the operands is of type string, the concatenation is treated as a string, and all other arguments are implicitly converted to the string type. String concatenation is not allowed on the left hand side of an assignment, only as an expression. The bulk of the stuff added to Verilog for SystemVerilog was a copy and paste from Vera, and was mostly for verification. As a result the constructs are mostly unsuitable for hardware design/synthesis - and nobody (else) wanted to fix that. I was ...

    Shift Operator - Verilog Example

    Shift Operator <<, >>, Verilog Example Create shift registers, shift left, shift right in your FPGA or ASIC. The shift operator in Verilog is used to shift data in a variable. The left hand side of the operator contains the variable to shift, the right hand side of the operator contains the number of shifts to perform. When you go to edaplayground, choose the Modelsim simulator to run these. Riviera-PRO is currently the only other SystemVerilog simulator choice on edaplayground, and it messes up on the tricky ones (more on that in a bit). These examples demonstrate using the streaming operator to do these conversions: unpacked array of bytes to int

    Streaming operator for unpacking a bitstream - UVM ...

    Im stuck on a problem I encountered with a use of the streaming operator to unpack into a dynamic array. Rather than write procedural code, I thought I could use it actually with some amount of success. Here is what the code more or less looks like: uvm_pack_bitstream_t bit_vector; bit bit_array[... Concatenation Operator - Verilog Example. The Verilog concatenate operator is the open and close brackets {, }. It should be mentioned that these brackets can also be used to do replication in Verilog, but that is for another example.Concatenation can be used to combine two or more types together.

ISSUE with 11.4.14 Streaming operators (pack/unpack) if the size of source not even By karandeep963 , December 1, 2014 in UVM SystemVerilog Discussions Reply to this topic Q16: Is uvm is independent of systemverilog ? Ans: UVM is a methodology based on SystemVerilog language and is not a language on its own. It is a standardized methodology that defines several best practices in verification to enable efficiency in terms of reuse and is also currently part of IEEE 1800.2 working group.

    SystemVerilog Streaming Operator: Knowing Right from Left

    SystemVerilog has this cool feature that is very handy for converting one type of collection of bits into another type of collection of bits. It's the streaming operator. Or the streaming concatenation operator. Or maybe it's the concatenation of streaming expressions (it's also called pack/unpack parenthetically).

    Streaming Operator The streaming operators perform packing of bit-stream types into a sequence of bits in a user-specified order. When used in the left-hand side , the streaming operators perform the reverse operation, i.e., unpack a stream of bits intoone or more variables. Re-Ordering Of The Generic Stream Hi guys, I cant figure out how to take multidimensional array such as: bit unsigned img ; And make this array as a stream of bits. Think of it as an 4X4 image that each pixel is 11 bits in my memory that I want to read, and I have 1 input pin that get my image as a stream of bits, I prefer if you have any idea how to do that, to get the data in streams of 11 bits (lets say I have a typedef). SystemVerilog first saw public light of day as an Accellera standard way back in 2003. Vendors rallied behind it, users were enthusiastic, and Accellera wisely passed the standard into the care of the IEEE. The first gold-plated, fully-official IEEE SystemVerilog standard appeared in 2005.

    Because an image is worth a thousand words, I’ll use graphics to show how to use the streaming operators and how the individual bits are affected by the stream operators. 1.

When we need to pack several variables into a single variable, we can use the left-to-right streaming operator 다음을 VCS로 실행하면 아래와 같이 나온다. 무엇보다 Reverse bit 연산이 매우 쉬워졌다. 이전 Verilog로는 for-loop를 써야 했었지만, SystemVerilog에서는 {<< {j}} streaming operator로 간단한 구현이 가능해졌다. When connecting up array of instances of modules that have only single-bit ports (such as a flip-flop), often all you care about is that the port expressions have an equal number of bits. The generic way to write this is with an extra level of hierarchy and the >> streaming operator of 11.4.14.
