When does the tick go high in Verilog?
When the fast input is low, the output tick is high for one cycle every 150 ms (every 7500000 cycles) The clk period is 20ns. If the fast input is high, tick should go high for one cycle every other clock cycle.
How often should tick go high in CLK?
If the fast input is high, tick should go high for one cycle every other clock cycle. I’m thinking that I should count the clk cycles and use the count to output tick as high when the number of cycles are met but I can’t seem to get it to work.
How does the Verilog operator yield the remainder?
Verilog – Operators Arithmetic Operators (cont.) Modulus operator yields the remainder from division of two numbers It works like the modulus operator in C Modulus is synthesible 3 % 2; //evaluates to 1 16 % 4; //evaluates to 0 -7 % 2; //evaluates to -1, takes sign of first operand 7 % -2; //evaluates to 1, takes sign of first operand
What does always Block mean in HDL-Verilog?
Instead, it indicates when the register/latch specified in the block needs to change states, typically on a clock edge (register) or level change (latch). If you’re trying to detect an edge on an input, such as for an interrupt detection, the recommended way is to synchronise the edge to an internal shift register.
What is the purpose of timing checks in Verilog?
Verilog contains many timing-check system tasks, but only the three most common tasks are discussed here: $setup, $hold and $width. Timing checks are used to verify that timing constraints are upheld, and are especially important in the simulation of high-speed sequential circuits such as microprocessors.
Where to find Verilog RTL models for stdcells?
I have a stdcell library which has “.v” file which contains all Verilog RTL models for stdcells. This stdcell library also has a “.lib” and “.db” timing files with all the delay information for these verilog stdcells. This “.lib/.db” files have been provided to me by stdcell IP vendor. I want to run AMS simulation in Cadence Virtuoso environment.
