I am trying to build an 8-bit CPU with a 5-bit opcode, but sometimes when it tries to execute an instruction, usually the ones that have to write to memory, instead of bringing the R/W line high, it gets stuck in an infinite loop between the intended result and null until the next clock cycle. I have no idea why this happens. Here's the link. https://circuitverse.org/users/98716/projects/test...

I'm trying to simulate a specific ram chip, but it uses bidirectional data pins. So far as I can tell there are input and output pins, but no way to combine them.

Is there a way to make unconnected inputs high (for NAND gates)? They seem to be low when they're unconnected

I want to select multiple components, but not select the whole circuit, so I can drag those components somewhere else or copy and paste them. Can I do this some how?

I tried having a constant (1) going into an AND gate, then a NOT with a cycle. The simulator complains heavily and I don't have any waveform coming out showing the expected oscillation. This is what I'm referring to: https://en.wikipedia.org/wiki/Ring_oscillator#:~:text=A%20ring%20oscillator%20is%20a,fed%20back%20into%20the%20first. Any pointer is most welcomed.

I was working on an online project the last couple of days and today when I try to log in back it just gives me the blue saving icon indefinitely, not allowing me to edit/download/save/ or do anything in the project. Tried another browser (Chrome then Firefox) but nothing changed. I just need a copy of the project at least so I can continue working peacefully.

Comparing 32-bit values with bitwise XOR is resulting in undefined bits. https://circuitverse.org/users/120210/projects/xor-gate-tests

Under the "Misc" tab, there is an item called the Force Gate. It's tooltip says "ForceGate Selected." which doesn't help. I am confused as to how to use the Force Gate, and it doesn't seem to be documented anywhere either. Please help!

Is it possible to get the Clock faster than 50ms? i found a way to double its speed up to 25ms but thats still too slow for my needs. Thanks for reading

I have a simple circuit using some latches and tri-state drivers. On one clock, I get a stack overflow message but it is not obvious why. The fault occurs when the WR input is manually toggled from 0 to 1. The Verilog text is here: /** * This is an autogenerated netlist code from CircuitVerse. Verilog Code can be * tested on https://www.edaplayground.com/ using Icarus Verilog 0.9.7. Thi...

Is there any page where you discuss the Verilog limitations, bugs, errors, etc. in CircuitVerse or any kind of documentation on the language?

為什麼circuitverse verilog 在設計時運行都沒有問題,也可以顯示功能出來。 但是,上傳分享後,都不行運行?為什麼 我的範例如下: https://circuitverse.org/users/102221/projects/testnotdemo https://circuitverse.org/users/102221/projects/case-demo

Whenever I load the instructions to ROM memory and enable the clock to start execution, I get the error "ConstVal set to non-binary value". What does that even mean? Any help would be much appreciated. Thanks! This is my project: https://circuitverse.org/simulator/edit/hack-computer-16-bits

Help I am trying to get a bus which many chips can talk to, a very simple 8 bit CPU, problem is I keep getting the error "ConstVal set to Non-binary value.", this is odd as only one thing outputs onto the bus at once, but two chips are connected the program counter and Accumulator. https://circuitverse.org/users/80606/projects/alu-1e047f5a-390d-4109-9699-8d866e792af7
