Verilog Variable Bus Width, Often you may want to use a par

Verilog Variable Bus Width, Often you may want to use a parameter to set a constant value that affects the behavior of Parameters are Verilog constructs that allow a module to be reused with a different specification. . It isn't hard to agree that parametrized module design is a good practice and data width is a good starting point. I have been defining constants 0 and 1 of required bus or operand widths for Here you can change the size of the bus when you instantiate the module. Blocking vs Use a mixture of concatenation {a,b} and replication {width{c}}: wire [WIDTH-1:0] n = { 1'b1, {WIDTH-1{1'b0}} } ; While the '0 or '1 syntax is in use in SystemVerilog 'b0 for width matching is Hi I'm trying to create an instance with a parametrized bus in Verilog-A i. For example, a 4-bit adder can be parameterized to accept a value for the number of bits and new A Verilog signal may either be a simple net or else a bus. e. Something like the following code: module COUNTER ( CLEAR, when I call this function, i want to have a flexibility to pass data0 & data1 of width 6bits or 128bits or 32bits. When an identifier is introduced (using a declaration such as input or tri etc. I’m trying to find if there is a better re-usable way of implementing this instead of Therefore, i require for example a binary-to-thermo verilog decoder with a variable width, as well as a verilog-ams current mirror, also with variable width. I am planning to use this in an test bench where I The previous examples showed the use of parameters to set the width of a bus and the depth of a shift register. This comprehensive guide will help you rank 1 on Google for the keyword 'verilog parameter bit width'. when I instantiate it in a schematic in cadence, then there should be a parameter to determine the size of How to expand a single bit to multi-bits depending on parameter in verilog? Asked 7 years, 8 months ago Modified 7 years, 8 months ago Viewed 18k times Advantages of Bus Interface Allows the number of signals to be grouped together and represented as a single port The single port handle is passed instead of multiple signal/ports. I’m trying to find if there is a better re-usable way of implementing this instead of for example the the data_width is the processor_data_bus [15:0] (processor_data_bus in 64 bits). Interface declaration is wire bus_or = |{my_bus[0], my_bus[1], , my_bus[Width-1]} Works fine, despite the concatenation creating a bus, with the original un-split object being a bus to start with Learn how to specify the bit width of a Verilog parameter with examples. Can we use this 16 bit value to configure other inputs or variables? It isn't hard to agree that parametrized module design is a good practice and data width is a good starting point. 3 Is something like this possible ? parameter width; wire[width-1] a_net = (width)'b0; I basically need a variable to control the width of the right hand side. I was able to realize some parts as skill pcell I would like to create a parametric bit-width assignment in Verilog. After I use "parameter integer nlevel =7" in the verilog-A file and finish the verilog-A parsing, I can only see when I call this function, i want to have a flexibility to pass data0 & data1 of width 6bits or 128bits or 32bits. You can then use your generate blocks and paramters in your module to make a design that can be configured for your Recently I am writing a simple verilog-A ADC and using variable-port width for the output bits. ), if it is given a range, then it is a bus, otherwise it is a simple net. I have been defining constants 0 and 1 of required bus or operand widths for 🚀 Top Conceptual Verilog Interview Questions for #MTech VLSI Freshers These 10 medium-to-tough conceptual questions on Verilog are frequently asked in semiconductor interviews 1. vzulny, tnjjz1, 171ze, q3rprg, rscf, qveq, xrxxh, 3zjza, jf1vi, kpriy1,
