<h1> sch-rnd - plans for 2023 </h1>
<p>
With the support of <a href="https://nlnet.nl">nlnet</a>, the following
features <b>have been implemented</b> in 2023 and 2024:
<p>
<ul>
<li> hierarchic design (sheets referencing other sheets as "subsheets" for repetitive parts) [1.0.5]
<li> alien file format: load sheets of tinycad and altium and orcad [1.0.4]
<li> non-graphical sheets (data or scripted) [1.0.1]
<li> raw spice target and export (ngspice and gnucap) [1.0.1]
<li> simulation target (SPICE) [1.0.2]
<li> symbol attribute based build options and DNP for the PCB workflow [1.0.2]
<li> symbol editor mode (directly opening a symbol file for interative edit) [1.0.3]
<li> back annotation upgade from pcb-rnd [1.0.3]
<li> symbol attribute based alternate MCU pin function system [1.0.3]
</ul>
