I would like to use icestudio in class e.g. to demonstrate the simulation of logic gates. Ultimatively I would like to create logic tables with the students.

I found following two descriptions but - unfortunately - do not speak spanish:

Just spent about half an hour trying to figure out how to use and/or install the Library Manager gui into the IDE My IDE (2.0 beta 2) doesn't match the docs in a handful of places. Specifically, the following imply that there is a Library Manager gui, which one might assume has to be installed separately:

The Sphinx documentation flow was extended by several sphinx and third party extensions. These extensions should be documented along with their modifications. A comprehensive syntax guide should be assembled, to collect all syntax notations at one place instead of dozens of third party documentation websites with partially poor usage descriptions.

The SCons file is quite "magical" and undocumented at the moment. I needed to find it to understand these points for example:

• how is a PCF file located? which is chosen if there are multiple?

    def vivado_resources(self):
        report_path = self.out_dir + "/" + self.project_name + ".runs/impl_1/top_utilization_placed.rpt"
        with open(report_path, 'r') as fp:
            report_data = fp.read()
            repo

Vendor tools dram tests were not enabled until #1234 got merged.

With SymbiFlow/symbiflow-arch-defs#1268 I have temporarily disabled the vivado_targets, to let CI go green (as it has been red for too long now).

This issue is to keep track of the problem with DRAM evaluated on vendor tools with fasm2bels.

保存高质量的 png 文件，同时文件比较小，pdf 文档实际是 png 图片

# install.packages('devtools')
devtools::install_github("r-lib/ragg")
