Compatibility for record port types (name mangling), for e.g. post synth test benchs

Hi Tristan, Thanks again for the fixes to the demux. That has allowed us to take a look at both ilang and verilog dumps from Yosys. I would like to...

The scripts have some hard coded fill and decap cells, in platforms/sky130A/fill_cells.yml and sky130_fd_sc_hd.v. These have to be in sync or the netlist checks fail. Suggestion, instead of hacking these:...

Documentation error?

Caveat: I've not simulated the netlist... Is it not the case that for 1RW1R RAM: - In https://raw.githubusercontent.com/Cloud-V/DFFRAM/main/docs/img/ram_1rw1r_ifc.png since EN0 rises and WE=0000 in cycle 2, that Do0 should output...

Row decoder logic messing up the placement of arrays where row size is a multiple of word size.

Thanks for making this tool. The latest change sets (Mar 21) solve most of the issues we were seeing, except this one. We had previously done reg files with latches...

Yosys synthesis

Here is a patch that will allow the boot loader to synthesize with Yosys. All of the changes are simple, and allow the RTL to pass Yosys rather strict syntax...

I use the Local Installer

### Prompt As per the installer log message: [ALERT] The local installer is deprecated and will be removed in a future version of OpenLane. If you're still using it, please...

Add gate level simulation verilog to PDK.

I needed to simulate the gate level netlist for DFFRAM, but I found that no combination of defines results in functional results with icarus verilog and sky130_fd_sc_hd.v as installed by...

Crash with binary data.

Thanks for the great work, I have a number of these devices connected to instruments here and there, incredibly useful. I'm atm working with a Tektronix scope, trying to get...

Attribute of component (e.g. keep) not kept in the synthesis netlist

7

**Description** When using the GHDL plugin to yosys, and probably more generally, attributes are not attached to instantiations. This causes (for example) yosys to optimise away instantiated blocks that are...

Quick hack to fix compatibility with OpenROAD from OpenLane 2.0.8. Without this change, DFFRAM fails with: [CRITICAL ODB-0001] No logger is installed in odb. [15:32:37] ERROR Subprocess had a non-zero...
