I will get an RC-1 of the macOS builds out early next week. I need to rekajigger it so wx builds without debug asserts. Adam On Thu, Oct 31, 2019 at 7:26 PM Holger Vogt wrote: > > > > Do we want to switch to this for the next stable release? If so, what > > is the procedure for making sure

Do we want to switch to this for the next stable release? If so, what is the procedure for making sure it's tested? Adam I have assembled some test circuits. These include the 4 demo circuits delivered by KiCad and some others, simple and more complex ones. You may find them at

My analysis of threadrippers vs top of the line Ryzens, condensed in 2 points: 1. For significantly more money you get few more cores, a lot more PCIe lanes and 20-30% less frequency (single thread performance). 2. Unless you know that your workload is easily parallelizable to 50+ threads,

Good to know. I didn't realize the gen 3 threadrippers were not out yet. I may have to rethink my build. Thanks, Wayne On 10/31/2019 9:57 AM, Jon Evans wrote: > I don't own either, but am planning a Ryzen build.  The Threadrippers > built on the third-gen Zen are not out yet, but presumably

I don't own either, but am planning a Ryzen build. The Threadrippers built on the third-gen Zen are not out yet, but presumably they will be even better as workstation/server CPUs than third-gen Ryzen. On the other hand, if buying parts today, the 3900X / 3700X seem like way better bang for the

Hi Adam, I would think so if we to fix the crash bug on macos. We would need a 5.1.5-rc1 build with ngspice 31.3 so users could test. I would hope one or more of our macos devs would also test this using our spice demos to at least confirm that things work as expected and that the crash bug has

For convenience, I created the following schematic symbol, and this subcircuit: .subckt DIFFMETER a b out1 out2 BV1 out1 GND V=V(a,b) R1 out2 GND 1g .ends By putting the pins out1 and out2 in the same location, hiding out2, I could trick KiCad to consider any wire/label there connected. It
