<h2>V0.0.1 Known Limitations<a class="headerlink" href="#v0-0-1-known-limitations" title="Permalink to this headline"></a></h2>
<p>The following is a list of known issues with the V0.0.1 IP:</p>
<p>It’s possible that one or more NPC.2 drc violations can occur (see drawing below.) When the extent of the abutment of npc layers between two cells differs too greatly a notch can occur. This can be fixed by moving or replacing one of the cells.</p>
<p>This error can be prevented by making changes to the way that cells are placed by the EDA tools. This placement-postprocessing scripting fix has not been implemented at this time.</p>
<p>NPC.2: 0.27 min. spacing/notch of npc:</p>

<ul>
<li><p>In our testcase a single npc.2 DRC violation appeared. This violation refers to a notch between polygons of npc (95.20) inside standard cells that abut. This problem is being investigated. A simple fix at this time is to move the offending cells to new locations.</p>

<h1>Overview<a class="headerlink" href="#overview" title="Permalink to this headline"></a></h1>
<p>The SkyWater SCS8MS Release Notes contain information regarding the low voltage high speed standard cells available from SkyWater for this technology and its known limitations.</p>
</div>
<div class="section" id="ip-usage">
<h1>IP Usage<a class="headerlink" href="#ip-usage" title="Permalink to this headline"></a></h1>
<p>The SCS8MS IP contains a variation of standard cells that utilize low voltage high speed logic blocks in the SKY130 technology.</p>
<p>The scs8_ms library contains two OA libraries, including a techLib reference library. The only library the designer will need to use for these standard cells is scs8ms. The remaining libraries are necessary as references to this one only.</p>
<p>A list of these standard cells is not available in V0.0.1. For additional information, please contact SkyWater Technology.</p>

<p>The simple “sv_interfaces” design example was used as the RTL base. Genus synthesized a netlist. The netlist was visually inspected to see what types of standard-cells were included; netlist included DFF, NAND, XNOR, etc.  No effort was spent analyzing performance, power, or area (PPA) nor whether the SDC was consumed correctly.  Intent was just to verify that a structured netlist was generated.  Numerous reports were generated during the synthesis process (area, gates, check_design, etc).  A quick inspection of the report files was done just to see that no gross errors were present due to input-file consumption.</p>

<p>The simulation was run with both the RTL and the netlist instantiated in the testbench side-by-side.  Visual inspection of the waveforms of the two modules revealed that they appeared the same.  Whereas the netlist is consumed as gates by the simulator, no effort for SDF-annotated simulation was expended.</p>
