# Questions
-TODO
+Dear Jean-Paul and Luke,
+
+you applied to the 2019-10 open call from NLnet. We have some questions
+regarding your project The Libre-RISCV SoC, Coriolis2 ASIC Layout
+Collaboration.
+
+Can you provide a breakdown of the amount requested? We understand there
+are a number of different tasks you will undertake, but we need to
+understand the cost composition of the proposal.
+
+Are Coriolis2 python bindings ready for the upcoming switch to Python3,
+as python2 availability is decreasing? The same actually holds for Qt4,
+do you plan to upgrade this - or would you be open to others doing that?
+
+nmigen is a tool produced by others, how will this work? Will additional
+cost be needed to upstream this effort? Would it not make more sense for
+that project to be funded directly?

+
+ I will let that point to Luke...

+
+ * For Qt 5, the port is already done and working. It was needed to
+ build for Debian 9 / Ubuntu 18.04 LTS.
+
+ * For Python 3, the move has not been done (yet), but I sure feel a
+ rising pressure to do it.
+
+ Long answer is that my "reference build system" is Scientific Linux 7
+ (a free clone of RHEL 7) which allows me to both run my tool and the
+ commercial ones as well (Cadence/Mentor/Synospys) and keep me close to
+ the OSes used in the industry. And this system still uses Python 2.7
+ as it's primary (RedHat makes very stable systems, but the downside
+ is that they uses old versions of tools). So, of course I'm aware
+ that I will need to switch to Python 3 at some point, but it doesn't
+ feel urgent.
+ I'm perfectly happy with other people doing the port, I'm just not
+ very proud about the way the Python bindings are done. As I want to
+ perform very specific operations, I did develop a bunch of C macros
+ to do the job. They work well and do exactly what I want and there is
+ even a tutorial on how to use them, but they are a bit clumsy and
+ not that easy to understand.
+ Portability across systems is a dependency nightmare, so I try
+ to keep to most commonly shared ones.

+
+ To muddle the point even more (this is an info I wanted to pass on
+ Luke), we are also investigating on nmigen in the LIP6, with the same
+ goal of interfacing with Coriolis.
